I was completing a roughly 2.5 hour flight from LatinVFR KEYW to Imaginesim TJSJ, and as I was touching down on the runway, I experienced an application hang. The sim didn't CTD, which I've experienced before, it just hung. The Event Viewer shows the error as an application hang, and doesn't identify anything other than FSX.exe as being at fault. It was my first flight on my rebuilt rig. I was in the NGX, with AS2012 active, Aivlasoft EFB, and the latest version of FSUIPC. A quick search of the forum didn't yield any conclusions about the cause of this type of error. Any ideas or suggestions would be much appreciated.

This appears to be one of those system errors where your application is running out of virtual memory. This happens frequently on long flights with FSX. Make sure your virtual memory (page file) setting is set to 'System Managed Size'. FSX likes that setting better than one set manually. This includes putting the page file on another partition or other system drive. You have a very nice and powerful computer system but it looks like FSX brought it to its knees.

If it comes down to being a problem with the available memory (for FSX), also make sure to use the Highmemfix entry in your fsx.cfg. Highly recommended for the rather resource hungry birds like the NGX.

Hey guys, thanks for the responses! I have moved my paging file to another drive, and I went through my cfg file and found there was a typo in the highmemfix entry. We shall see if this fixes the issue. Again, I really appreciate all of the work you guys do to help members of the community. Thanks!

See CoolP? There are nice guys here! Thanks ramrunner for your kind comments. Always appreciated. Hopefully we have found a fix.

You guys deserve gold medals for the extents you go out of your ways to help stricken simmers.

Thanks again Rick! Most appreciated!

Thanks for the kind words, guys. Seems like the 'wisdom of the crowd' is the thing to help a lot of guys around. Lets keep it that way. Glad being on the team with you.

Hi

 

now here's a thing. I have been getting crashes as well, usually after 15-20 mins the prog just freezes and have been searching your excellent site for possible rememdies.

 

Tried to find the FSX.CFG file but it was buried away in backup folder.

 

Where should thisd file reside please, should it be in the root folder for FSX?

 

Thanks

 

Eric

It is not in the FSX root folder, it is in C:/Users/(YourComputerNameHere)/AppData/Roaming/Microsoft/FSX. You must have hidden folders set to visible in order to access this. Also, if your OS is installed on a different drive than C:/., follow that same path, but on whichever drive has your OS.

 

Have you looked at the event viewer to see what the cause of your crashes are? We can be more helpful if you tell us what module was at fault, and what the error code was. I highly doubt the cause of your crashes was the same as mine. Also, what are your system specs (OS, CPU and any applicable overclock, RAM capacity/speed/timings, GPU, PSU, FSX version, and any addon's or tweaks you are running)? It might be helpful if you create a new thread for your crashes, as they are likely not related to the ones discussed in this thread.

" usually after 15-20 mins the prog just freezes " and "The sim didn't CTD, which I've experienced before, it just hung."

 

Download, this, guys, rename it as UIAutomationCore.dll and place it in the root folder of FSX.

 

The UIAutomationCore.dll is the single most common causes of freezing and hanging when using Windows 7, particularly the 64-bit version. UIAutomationCore.dll is an API and talks between the operating system and an application: in this case between Windows 7/64 and FSX. Unfortunately, at the time Windows 7 came out - FSX was End of Life and so this API was not tested with FSX - and it does cause a number of issues - certainly freezing and black screens. The answer to this is to use the Vista version, placing it into the root folder of FSX.

The original W7 version is 6.1.7600.16385. The version you need and should use is 6.0.5840.16386.

UIAutomationCore wasn't my problem, but could well be Homelyn's. I have the Vista version installed, and it would show UIAutomationCore.dll as the faulting module in the event viewer. It is a good tip though.

Some system details will be useful, Eric! Thanks.

I would be interested to know if those suggestions fixed your problem(s). Thanks!

Thanks for the help, will try it and report back.....
