Prepar3D v4 CTD at same location ntdll.dll

Recommended Posts


I flew LJLJ-EGCC for 2 times with PMDG 737 and my Prepar3D crashed at same location:

I saw on other forums and posts that it has something to so with heap corruption. I had 50-60FPS in flight and then I just got CTD. The only setting that I have changed from the time it was working normally was Level of detail radius. I moved slider from HIGH to ULTRA but I think that is not the cause.


My PC specs:

i7 7700

Windows 10 (Fall Creators Update)



KFA2 GeForce GTX 1060


Thank you!

I recently had similar crashes but received a StackHash (which is about the same as an ntdll.dll error as they interchange much of the time.  One crash showing StackHash as the error and other times ntdll.dll).  I recently posted a solution for a StackHash/NTDLL error with and Exception Code 0374 (heap corruption).  Probably the most common error in FSX/P3D ever.  Rename your P3D.cfg to, restart P3D and that should fix the problem.  As you can see later in the following thread, I also disabled mytrafficmil.bgl as that is a known cause for ntdll.dll errors if you have MyTraffic6 installed.

Thank you for help! I reinstalled the client, renamed the .cfg file to let Prepar3D rebuild the new one, set settings like they were before and I was able to complete two 1h flights (LJLJ-LOWW-LJLJ) without restarting Prepar3D v4.
