Prepar3Dv5.4.9 Random CTDs (0xc0000005)

Yes, I've already tried that. I've even reinstalled P3D. 

After the two latest CTD events last night, I might suspect the AI traffic injected by vPilot as the culprit. 

I was flying from LPFR to EDFH with a Boeing 737 (NGXu) yesterday. The first CTD occurred at 20:59z over Nantes at waypoint BAKUL. I reinstalled the NVIDIA driver and tried the exactly same flight again. This time I made it just over Spain. Same error, but at waypoint BARDI at 22:34z. I created a map with the help of Simbrief. There are no addons installed in this entire area between LPFR and ELLX, except ORBX Global and ORBX Freeware Airports. So my troubleshooting continues. There are 453NM between BARDI and BAKUL. The time between the CTD's is 1:35h. So I assume that some AI Traffic with a groundspeed of ~287 kts came towards to me, which is not compatible with P3D v5. 


The flight from LPFR to EDFH completed offline without any problems. Unfortunately, I have no idea how to verify this assumption. How can I find out if a certain AI aircraft is not compatible?

This seems to be a strange coincidence as to what @Ray Proudfoot previously saw, documented in another forum post here recently.

The 3 things he had possibly identified were Orbx, AI and P3D v5.4.


Of those, he rolled back to v5.3, I am sure he is stable now. You may want to try this. Make one change and test.

As @787flyerhas suggested this sounds similar to my random freezes / lockups I was experiencing. They started after I updated to v5.4. I never had them with v5.3HF2.

Since reverting I’ve not had a single incident so for me the problem was between AIG Ai and 5.4. You can test this yourself by reducing Ai traffic to zero and fly your troublesome routes. Make sure no other program is injecting Ai.

If you have no problems then revert to 5.3HF2. Clearly there is some incompatibility between some Ai BGLs and 5.4 but finding it is impossible.

My own experiences are here. https://www.avsim.com/forums/topic/640158-resolved-p3d-v54-random-lockups-driving-me-mad/
