I have decided to write this post even though I know the chances of getting an exact answer is slim, but perhaps someone can derive something from the error report, system configuration or add-on composition, later in this topic that I am not capable of or connect the dots to see the error in a way that I have not.
I am like a lot of other people suffering from the ntdll error in P3D V4 (and V3). I have had this error ever since the early versions of P3D V3 and have had it on a lot of different occasions counting more than 10-15 times over 1000-2000 hours of flying.
It usually happens on long flights but I have seen it happen in the NGX on a short hop in Norway and on a trip in central Europe. This could indicate that it is not connected to a location which some people seem to experience.
The CTD has appeared in the PMDG 737 NGX, 777, and 747 which could indicate that it is not connected to a specific aircraft.
On some of the flights I have seen it happen in correlation with big cloud systems but that is not consistent.
I have searched various forums for a resolution and I have been trying out whatever possible solution I could find, some of these being the ones in the Avsim CTD guide.
Some solutions indicate that an overclocked system could be the cause of this issue but I have seen the CTD even when running no overclock at all.
Some indicate that it could be caused by outdated drivers but all my drivers are up to date and I update them regularly(also chipset, disk, usb, sata ETC), so that in contrast to me having the CTD over such a long period would indicate that it is not driver related. In between all of this I have done a complete format of my PC twice, the CTD is still persist.
Some point toward couatl being the issue but again, the error have happened for such a long period of time that the chance of that causing it with all the updates it have gotten over the past year is slim.
Before someone tells me to try and follow the debugging steps given by LM by deactivating all addons and then testing them one by one. I agree that, that would be a good idea if you had oceans of time which I unfortunately don’t have. Given the fact that the CTD happens on such rare occasions, means that the debugging process could become very difficult and lengthy. Because in theory I could end up sitting and having to fly for 1 maybe 2-3 months with no add-ons installed before actually seeing it happen again, I’ll leave the beta testers to do that. I have on some occasions experienced a CTD free 5-6 months and then suddenly seeing the CTD pop up twice over a week without a pattern to how or why it happened.
On three occasions I have tried to recreate the exact flight where the CTD appeared and on none of them I have managed to trigger it again.
I am not looking for a definite solution here and now, because i am fully aware of how difficult this is to troubleshoot. But I am hoping maybe someone can guide me towards what direction I need to start looking.
With that in mind, thanks.

Various airport add-ons, but seeing that the error usually happens over water in the middle of the Atlantic would point me towards thinking that it is connected to a scenery
