FSX freezes after 1-3h of flight, and continues..

[Germania 0]

Hello guys,

my flightsimulator is 'broken'.

So.. for example, I fly United 777-200LR from KSFO to KMIA. After 2:20h my fsx got white and says 'No response'. If I click on the screen nothing happens. After 5-10minutes it continues with normal flying. 10-20minutes later, the fsx becomes white and everything repeat..

It happens with every aircraft

(PMDG)

MD11, 747, 777, 737

(WILCO)

Evo2

(CS)

757

(LVD)

767

(Freeware)

Dassault Falcon 50...

 

Help me please. I love to fly long-hauls but now I cant because of this problem. I also tried to set down my settings (water & LOD as in other threads predicted it would fix the problem), tried an external fps limiter, but now i'm at my end.

 

Please help me.

If you need i'll send the eventmanager log.

 

 

Greetings..

As stated in the AVSIM CTD Guide (located to the right of this forum under Hot Spots), long flights over an hour in length are usually caused by loss of Virtual Address Space (VAS). FSX shares 4GB's max with Windows. When it runs out, FSX will freeze or crash. Then if you pause for a few moments, VAS may be released and you have enough to continue on for a bit then crash or freeze. I think this happens with modern systems because you think you have a powerful system and you crank all the settings up, including Autogen and these actions eat up VAS super fast. Here's how to monitor the amount of VAS during a flight to see if this is happening to you:

 

Monitoring VAS in FSX or P3DV2 – The freeware or registered versions of the FSUIPC utility will allow you to monitor the amount of VAS remaining during a flight session. This might be valuable in troubleshooting Out-of-Memory (OOM’s).

 

Startup FSX/P3D and then enter the Addon Menu and select FSUIPC. Once FSUIPC is open, click on the Logging Tab and enter 024C under Offset and select S32 under Type. Select where you would like to have the usage displayed. The FS Window is for Full Screen sessions. The FS Title Bar is for Windowed Mode. AVSIM recommends you also check the Normal log file as this provides you information on how much VAS you had to start out with and then it logs usage throughout your flight.

 

The VAS usage is displayed in Kilobytes (KB’s). The value represents the amount of VAS left so, the lower the value, the more VAS being depleted. The max amount of VAS allowed in computers with 64 bit Operating Systems is 4GB’s. This is shared with other applications running in the background on your computer. For 32 bit Operating Systems, the max amount of VAS allowed for FSX/P3D is 2GB’s but this can be expanded to 3GB’s with a switch like the /3GB switch.

 

To convert the KB’s to the amount of GB’s, you should use one of the Byte converters on the Internet like the following: http://www.whatsabyte.com/P1/byteconverter.htm. You will never see 4194304 KB’s displayed as this equals 4GB’s. You might see around 3GB’s (3145728) remaining when you first start up FSX/P3D but that would be unusual. Do not be too concerned with the amount of VAS remaining when you first start up.

 

If this is not your problem, then please download and run AppCrashView as requested in the AVSIM CTD Guide and post the results of the crash here.

 

Hope this helps.

Well.. I didnt changed any Setting and it started to crash abruptly. Aswell I don't have fsuipc.

You don't have to change any settings to deplete VAS. You might be interested in a utility in our AVSIM Library called Quantum Leap which allows you to speed up your trip across the US or any ocean but it requires the payware version of the FSUIPC utility - http://library.avsim.net/download.php?DLID=179703 . The FSUIPC utility, freeware or payware version, will tell you when you are almost out of memory (VAS; not RAM) which is what is happening to your system (I'm 100% positive).

 

Best regards.

Noo.. I fly realtime on IVAO..

 

will test it and send the log here

Jim,

 

Many thanks for the detailed step by step on using FSUIPC to log VAS.

 

Greatly appreciated!

i have also this problem like many other people , freezes 8 minutes then its back no normal.

like many others already mentioned, it always happens over water, sea and oceans and never over land.
