P3D v4 freeze about 25 minutes after takeoff

Recommended Posts

Hello,

My PMDG 747-400 QOTS2 v3 freezes my sim shortly after departure.  It hangs a few times and then starts working again but only to lead up to the eventual CTD. No new scenery has been added.  It has worked flawlessly since the release but now I can't make it 100nm without a CTD.

 

Windows 10 64bit

nVidia Ge Force 1080 GTX 8vRAM

16gig RAM

i7700 4.4ghz

Orbx every land class

Active Sky 2016 for P3D v4

GSX

AivlaSoft EFB or FSC 9.6 for P3D v4

PTA 2.52

46" Monitor with 22"monitor for AivlaSoft EFB

Thanks for the help

Tom Dennis

Look at the event view to see if there is a faulting module.  Most momentary pauses are the simulator itself loading scenery objects but your description sounds more like an appHang which can be cause by any addon. I'd first try eliminating those, probably starting with that EFB stuff.

Hi thanks for the help.  Well it worked one time with a flight that lasted 2+ hours the event viewer stated a UTLive dll error as well as a AI dll error.  I uninstalled UTLive but it froze again just now.

What's your traffic set at in P3D settings?

My v4 crashes with this fault so can anyone tell me what is causing it from the log pic below?

Search ntdll.dll CTD P3D. I've gotten a few. Did some of the suggestions I found searching and they have cleared up (knock wood) and have done a few flights since.  One called for deleting a couple files related to the default scenario and letting P3D rebuild them which I did. This CTD keeps popping up, even after the Capt PFD pop up fix was implemented. There is something else that is going wrong and the only common denominator is this ntdll.dll being associated with PMDG aircraft and long flights and not every time which makes tracking it down much harder. The PMDG software is very complex and mixing with P3Dv4 in some sort of manner is causing this error. I never had them in P3DV3. I don't have any other 3rd party aircraft to do long flights with yet to see if it makes a difference. When Aerosoft releases the A330 I will try that one.

 One more such report just before reaching T/D on a flight from SBGR to EDDF on the 744 (P3Dv4.1),

I started to have micro freezes of a couple of seconds about 30 minutes before, and then a total freeze. This happened only with the 744, no such problem with the 777 on a longish flight from CYYZ (FlyTampa + ORBX NA) to SBGR (ORBX SA). Neither did I experience the same with the 744 on a "short" EGLL (UK2000 + ORBX EU) to KJFK (FSDT + NYC Drezynsky Design + ORBX NA). Although I had several freezes as well related to the sound issue which I cleared as indicated on your site. 

On all flights I had the same add-ons running with no issue.

When the final freeze happened today, my CPU (8700K) was using only 51% of its resources, RAM memory (64GB) was far from being fully utilised, neither was my GTX 1070.

This cannot be scenery related as I flew over Germany - and this region in particular - very frequently with other aircraft such as PMDG 737, FSLabs 320, PMDG 777 and Majestic Bombardier DH8C with the same AS16 + ASCA, Aivlasoft EFB, ORBX EU + Germany setup. 

Whilst I am convinced this may not be related at all, I did notice that my FMC showed the message that my nav database was out of date, which is not the case since I have an active Navigraph subscription and my database is up to date.

Another note for the sake of providing as much info as possible, when I click on the FMC "load flightplan", it said no plan available, when in fact it was correctly loaded...

A bit perplex about all those small hiccups.

Any input would be welcome.

Thank you.

Ntdll crashes point to not compatible addons. 

 

Get rid of any aerosoft scenery and airplanes if you have them. Any check all your other addons if they are surely updated to be p3dv4 compatible. 

 

In my case it turned out to be FSDT KJFK v2 to be the culprit that affected my crashes, even if ir is claimed to be v4 comp.

My PC is new (one month), so is my P3Dv4.1, so are all my add-ons strictly for P3Dv4 including all sceneries (my credit card knows better), this event happens ONLY with the PMDG 744 since as mentioned in my previous message, I used extensively the same scenery with other aircraft (including PMDGs) with no issues, so my P3Dv4 install and related add-ons are not to be suspected.

Using FSUIPC autosave?

Any yet no other PMDG 744 user is reporting this problem.  So your point is?

It has been suggested to me by PMDG support not to use the ACARS function in the FMC at all.  It potentially might be causing issues, especially during loading a saved flight.  I have also had no CTDs since I stopped using it.

Cheers,

Jean-Claude,

i also had repurchased and redownloaded sceneries. ONLY those which were sold as compatible. I had the same ntdll problems using the 747. Ntdll absolutely most of the time means there is anything installed into your v4 that is not compiled correctly. Search for ntdll on the p3d forums, using google, if you don‘t believe me. I had the problems in Europe, Asia, far away from New York and I somehow trust PMDG and RSR more than some scenery developers. And it definitely was a scenery. Since I have uninstalled it I haven‘t had a single crash anymore. I really recommend you untick all your scenery and then add it step by step. You can do this by developers to save time but I am sure this is your way to success.

Thank you Marc, I shall investigate that, the reason I brushed this possibility aside is that after two successive aborted flights due to crashes in very different locations with the 744, I successfully completed the same flight, with the same route, the same weather, the same traffic and the same sceneries with the PMDG 777!!! So my initial reaction was why would the 744 fail where all others (PMDG 737, FSLabs A320, Majestic DH8C) go through without issue? Logically if a scenery is the culprit, it should cause a crash each time I fly over or near it with any aircraft, but anyhow I thank you, I take your point and shall try. I fully trust PMDG products having used them for so many years since FS9, in this case the coincidences are troubling but do not prove anything.

Rudy I don't use ACARS but shall remember that point in case I was tempted to, thank you.

Kyle, I do have a FSUIPC 5 registered copy but don't use autosave, another helpful tip to remember, thanks. 

I am now in touch with PMDG support and shall dig further into this under their guidance, should the findings be of general interest I shall post them so as to help anybody else having the same issue. Thank you to all who tried to assist it is much appreciated.

The 747 is a new product that -afaik- uses p4d features while the 777 is still a „recompiled“ fsx addon... not to downgrade it. But I think there might be the issue. I also haven‘t experienced any crashes with the Airbus and regarding the Q400 I guess it‘s the most reliable and stable addon available... but looking at the way some sceneries have been ported into P4D I have no doubt the problems we have aren‘t airplane-made most of the time. 

I found this quite interesting: I had issues with orbx‘ Dubrovnik drawing water textures on the surrounding mountains. Also I had the island of Molokai completely covered with water textures. After I uninstalled kjfk all problems were gone, crashes and texture issues.

Just happened to me on a flight from VTBD to VTCC. Established on ILS36 and then just hung. P3D v4.
Could it be Navigraph moving maps?
No airports added.
Very frustrating.

I've heard of this before. It's a possibility.

I don't have it.

The most important question mark for me remains: Why the 744 and not the other planes (including PMDG's 773 and 738) under the exact same conditions - route, time, weather, traffic, scenery?

In my cases, SBGR to EDDF, the 744 crashed the first time when I started my descent after 10 hours of flight, the second attempt on the same flight plan, it crashed over the Canary islands on exactly the same route so one case does not relate to the next,  the 773 made it to the gate at EDDF with no issue at any time. I do not have any add-on at the Canary Islands or Africa, but quite a number in Germany and Switzerland.

From now on I shall exclusively fly the 773 and see if I get in a CTD anywhere or not. That's a challenge because it does not simplify the hunt for the cause...

I have the P3Dv4.3 and installed PMDG 747-8/8F v3 with Windows 10, 64 G RAM

For the first time in all P3D life in my system, the P3D freeze with 747-8 during the flight RJTT rwy 05 to RJAA rwy 34R

I might be missed something?

What rar archive? I only downloaded the PMDG installer from my account. I didn't see any rar file?
