Problem-

I am sure this is a problem with either the B77W or something route specific. But I haven't ever had any issues with the PMDG 772, mostly and only the B77W - I tried to fly the B77W from Heathrow to Tokyo a few months back, and 2 hours or so into the flight it crashes to desktop. I have completed many 772 flights and had zero issues, however with the 77W it's giving me a VAS leak.  This isn't the first time, but no issues with the PMDG 772 since I've got it, so this must be something to do with the 77W?

 

Detail -

 

BAW297 - Heathrow - Chicago (15th May 2015) - GSTBH (Stand 553) -

See below...

BAW297 - Heathrow - Chicago (16th May 2015) - GSTBJ (stand 545) - 

• Connect FS up at 1341z
• Connect to VATSIM
• Load up Active Sky Evolution
• Prepare for flight using real world data/loads and adding this into PFPX
• Load flight plan from CORTE
• I set the DEP/ARR page to what is likely to be the correct ARR into Chicago - WOBUN3G, 27L and PAINT4 ISL28C, ASP TRANS, VOGLR TRANS respectively.
• Download wind's from Datalink
• Pushback at 1510z
• Take-off at 1531z
• FSX crashes at 1747z just south of Iceland.  

 

The same thing happened yesterday, with a fairly similar route to NAT TRACK C and the same sort of detail as provided for DOF 160515

 

I use the following scenery -  Heathrow UK2000 (Latest Version) and the latest version of PMDG today, with the previous version yesterday.

 

ROUTE - N0485F340 WOBUN3F WOBUN DCT WELIN UT420 TNT UN57 POL UN601 ABEVI UN590 GOW DCT ERAKA/M084F350 NATC DORYY/M084F360 DCT ROUND/N0481F360 DCT ASP PAITN4

 

VAS started off at 2.4GB (From a Stand on Terminal 5) - a few change of views to just have a look. (I mean it is a game, we do take screenshots)  So in just over 4 hours there's VAS increase of 1.6GB overflying the UK (With no add-on scenery and the North Atlantic ocean). I was watching this continuously increase as we kept flying.

and the latest version of PMDG today, with the previous version yes

Do you mean PFPX? Have your entered a KORD runway into the FMC?

Have you tried without any weather, scenery, or AI?

Same as Kyle:  Start eliminating things.  Active Sky Evolution was for FS9, have you added textures to it? I'd be looking at the weather engine first since you are eating up VAS over water.  Also, it is puzzling that the B77L is okay but you have problems with B77W - they are pretty much the same thing code-wise.  The screenie you attached with the skin missing is indicative of low memory so I assume that was taken after you hit the wall on VAS.  Also, make sure you don't have any photoreal scenery loaded other than your departure EGLL.

Have you tried without any weather, scenery, or AI?

I have just tried the following. Heathrow, London City and Luton Extreme Deactivated. Default LHR. Active Sky Evo. No VATSIM connection.

(Changing of views, VC> Spot View > VC, but not excessively etc)

 

VAS LOG at Default Heathrow - Does this look normal?

2.170GB @ 1849z
2.359GB @ 1917z after setup for KORD (FPL and perf data loaded/FD setup for departure)
2.468GB @ 1942z
2.509GB @ 1949z
2.712GB @ 2108z
2.725GB @ 2117z - 1hr after setup for KORD

I very much doubt that it will be Active Sky Evolution, that's never caused me issues in the many years I've had it. 

 

Do you mean PFPX? Have your entered a KORD runway into the FMC?

 

That is correct, I entered everything as per flight plan into FMC.  Loaded CORTE and then added DEP/ARR for both EGLL/KORD into the FMC.  Once that was done, I then loaded wind-data from uplink. I am just going to park up the 77W overnight at Heathrow with V3.06 installed (Latest Version) and see what the VAS log says. Gives me the best test.  Currently parked up at Stand 545, with Active Sky on.

2.310GB @ 2122z (Start-up)  FSX, Heathrow UK2000 V3.06 and latest version of PMDG 77W
2.599GB @ 2154z (Cold mode, but with GPU on) 
2.614GB @ 2204z (In 10 minutes a 0.015gb (15.88mb rise))

 

Is that sort of VAS usage correct? On both logs.

 

Same as Kyle:  Start eliminating things.  Active Sky Evolution was for FS9, have you added textures to it? I'd be looking at the weather engine first since you are eating up VAS over water.  Also, it is puzzling that the B77L is okay but you have problems with B77W - they are pretty much the same thing code-wise.  The screenie you attached with the skin missing is indicative of low memory so I assume that was taken after you hit the wall on VAS.  Also, make sure you don't have any photoreal scenery loaded other than your departure EGLL.

 

 

Active Sky Evolution was released in 2010/2012 no? So surely it was for both, or are you adding it's FS9 coded and works with FSX, whereas ASN is better for FSX? If so I'll look into purchasing it soon. I have no photoreal scenery, as I only really see the benefit of having the airports when considering most of my flights are long-haul/short haul airline ops.  I got the screenie just before OOM, that was at 3.7GB VAS. I have done quite a few flights in the PMDG 77L.  I have just had a look, I've done zero completed flights with the B77W since I got it.  

BAW5 to Tokyo OOM'd in July 2014
Yesterday and today I got an OOM for the BAW297 to KORD.   

I have completed the following flights since July 2014 in the B77L. None in the 77W.

EGKK-KJFK and KJFK-EGKK (UK2000 & FSDT) EGKK-KMCO (UK2000 & Taxi 2 Gate) - October 2014
KMCO-EGKK -November 2014
EGLL-KJFK (UK2000 & FSDT),   
EGLL-OMDB (UK2000 and FlyTampa Rebooted) - February 2015
KJFK-EGLL, 
EGKK-TBPB-EGKK (No reset of Flight Sim), 
EGLL-OMDB, 
EGKK-MMUN and MMUN-EGKK (Payware Scenery for Cancun, Barbados Freeware) - April and May 2015.

I do find it all a bit strange.

Edited May 16, 201511 yr by concordeba

Not specifically related to your problem, but I stumbled upon your thread and noticed that you used Bojotes tool for tweaking FSX..

Im not sure what system you have, but I would in general not advice anyone to use bojotes tweaks anymore as they are simply, what I would argue, outdated with the knowledge we have now and hardware..

 

 

Eg. What does ProcSpeed=8885 do?

 

TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=4500  ??
TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=3000 ??

I for sure dont have them, and I have never been happier with my config.. My system seems to be worse then yours

 

 

I would strongly suggest you generated a new FSX.cfg, and used Tabs' guide for setting it up.. Or some PMDG guide, as its very good

 

Of the top of my head i Think the only four mods I have added to my CFG is Highmemfix=1 wideviewaspect=1 texture_max_load=2048 and the AM tweak..

 

You are welcome to send my an PM or quote me here if you need any assistance..

During the last round of VAS testing that we did for latest B77X, all tests were run with no weather and no traffic, same airports and routes, changing only one variable at a time.  That eliminates unknown variables.  Tests were run with both B77L and B77W and we saw no difference but that is not to say you're hallucinating.  You may be onto something and the big payoff comes if you can narrow down the problem to just the B77W in a specific scenario where the problem is repeatable.  Then others can run the same scenario and expect to get the same problem, which leads to the solution.

 

Active Sky Evolution is probably just fine... I was just looking for anything.  I don't think the problem is in your fsx.cfg either but making a backup and running it once with minimum tweaks is something you could put on the to do list as you are troubleshooting.  But, first priority should be getting a well defined scenario that we can repeat.

I would perform a full reinstall of ActiveSky (and perform testing without it).  On my system, I had higher-than-normal VAS usage and stutters after one of the ASN patches last year.  Reinstalling seemed to resolve the issue.  Correlation isn't causation, naturally, but it is indeed time to isolate variables.

Robbie,

 

I agree with all that's been posted so far.  However, from the data you supplied, I don't believe you are using the correct method to determine how much Virtual Address Space (VAS) you are using or that you have left.  This takes you to en excellent write-up on what VAS is as well as a link to a free tool (Process Explorer) you can download from Microsoft's Mark Russinovich.  This tool shows you how much VAS you are currently using. 

 

You can also use FSUIPC to measure VAS, and this method shows how much VAS is remaining. Here's a link to an excellent explanation and easy instructions on how to configure FSUIPC.

 

Hope this helps a bit,

Okay, so we know you OOM on a EGLL-KORD flight. Try KORD-EGLL with the same settings you are using on your westbound flight. See if that one completes okay. And don't use time compression or acceleration or whatever it's called. Don't change the cfg file for now. After we see the results of this eastbound flight, we can probably move on to the no weather/no traffic that Dan Downs mentioned. This needs to be done in a methodical way. You can't just start trying everything at once. Do the eastbound flight and see what happens.

Not specifically related to your problem, but I stumbled upon your thread and noticed that you used Bojotes tool for tweaking FSX..

 

 

I definately need to re-do my CFG, if you fancy helping that would be appreciated. Many years ago I was stuck on Flight Sim and had nothing better to do, now I have been working since I built this PC (The above flight list show's I hardly get the time anymore) - It does need a clean up and to get far better performance.

I am definitely onto something,  I removed London City Extreme V1.00, Luton Extreme, Gatwick V3 and Heathrow V3.03

 

Re-Installed Gatwick V3 and Heahtrow V3.06 - so far more stable.

Here is the results from last nights test, the sim is still running.  This is post running a complete re-install to the latest versions of UK2000. Maybe they was giving a memory leak?  However could it be the addition of the SID/STAR setup?

2.310GB @ 2122z (Start-up) FSX, Heathrow UK2000 V3.06 and latest version of PMDG 77W

2.614GB @ 2204z (In 10 minutes a 0.015gb (15.88mb rise))
2.634GB @ 0653z
2.650GB @ 0729z (after sitting at stand 545 all night)

Hello, I am using Process Explorer and Virtual Size - menu -> View -> Select Columns -> [Tab] Process Memory -> [check] Virtual Size -> OK. - It's been stable all night.

I am sure this is a problem with either the B77W or something route specific. But I haven't ever had any issues with the PMDG 772, mostly and only the B77W - I tried to fly the B77W from Heathrow to Tokyo a few months back, and 2 hours or so into the flight it crashes to desktop. I have completed many 772 flights and had zero issues, however with the 77W it's giving me a VAS leak.  This isn't the first time, but no issues with the PMDG 772 since I've got it, so this must be something to do with the 77W?

 

Do you have the latest update installed? If you installed it simply clicking repair it, then most likely you did not successfully install the latest update.

 

To check if you do have it or not. Do this in both the -200LR and -300ER.

 

Enter and activate a route, fill out the PERF INIT pages, and then go to the VNAV CLB page and change the CLB speed by manually inputting 325 as the CLB speed. If it gives you a invalid entry message in the scratchpad, then you do not have the latest release!!!!!!! (limited to 320kts in the previous release). If it accepts your entry of 325 then you have the latest release.

 

Now assuming you dont.... continue below.

 

KORDs missed approaches have the code that was causing the VAS leak in the previous PMDG 777 version. That leak was fixed with the latest update on May 7th. I also had a VAS leak leading to a OOM crash while flying to KORD with the previous version. KLAX, VHHH and plenty of other airports had the same code causing the VAS leak and crash. Otherwise no OOMs for me outside of these airports.

 

Here is what I suggest,

 

1. Open operations center, it will take a snapshot of your installed liveries. Close operations center when it is done loading up.

 

2. Uninstall the -300ER, uninstall the -200LR base package (in this very order).

 

3. Install the latest -200LR base package release, and then install the latest -300ER base package release (in this very order)

 

3. Then fly to KORD from EGLL again. You will not encounter the leak anymore. UNLESS....it is caused by your settings.

 

I have flown to KORD twice since updating to the latest release, both 13 hour plus flights, and no VAS OOMs. My rare OOMs were purely due to the now fixed memory leak caused by the missed approach code.

 

Report back!

Hello,

 

I think you might be right, when I entered the DEP/ARR into the FMC, I've had a VAS leak. I use Navigraph, so what I will do is completely re-install PMDG 777, as even though I tried what you said. Simply clicking repair hasn't done the job?  Was RJAA (Tokyo Narita?) also one of these airports that caused the Memory leak.   Either way it's definitely something happening once I've setup the FMC.

 

2.310GB @ 2122z (Start-up) FSX, Heathrow UK2000 V3.06 and latest version of PMDG 77W
2.599GB @ 2154z (Cold mode, but with GPU on) 
2.614GB @ 2204z (In 10 minutes a 0.015gb (15.88mb rise))
2.634GB @ 0653z
2.650GB @ 0729z (after sitting at stand 545 all night)
3.103GB @ 0827z (After setting up FMC)

Thanks all for your help.

 

 

Simply clicking repair hasn't done the job?

 

REPAIR is not the same as update.... REMOVE then install.  Check version in Ops Center to verify you are current.

Like Dan said, COMPLETELY remove the aircraft and reinstall it.  This does indeed sound similar to the bug we discovered, which has since been fixed on the latest, full installer.
