747-8 ntdll.dll Crash

[acamp04]

Hi everyone,

I tried to do a flight in the B748 from PANC to VHHH tonight and got this error about 6 hours into the flight. If you need anymore information please let me know!

As you're on P3Dv4 it is likely an incompatibility with any addon, that isn't completely compatible with version 4. If you have addon sceneries installed please check that they are 100% made compatible with v4. There are indeed still some developers out there (mainly scenery) who haven't understood the importance of a proper recompilation.

 

Of course this issue can also be different but very likely you will find the culprit in your addons.

Thanks for the quick reply. I haven't had this issue at all until I installed the updated 744 and the 748. Nothing has changed in my sim except those two items.

Correlation is not always causation. I’m willing to bet you flew over some incompatible scenery at about that 6 hour mark.

Check out the AVSIM CTD guide for common issues. That referenced dll isn’t ours.

Yep, started reading up on the guide. 6 hrs in I should've been over the ocean or Eastern Russia which would have just been orbx world and vector scenery. Thanks again.

I also got a CTD last night with ntdll.dll. And I can see from project fly that I didn't fly over any airport when the crash happened. My guess is it crashed when the auto step climb happened. Was also about 6 hours of being loaded into the plane.

I had an ntdll crash on my first too, about 6 hours in. From EDDF to KBOS

I also did PANC - VHHH and I had no issues. Which other sceneries covering that route do you have active?

For reference, I used:

PMDG B747-8

GSX Level 2

Activesky ASN + ASCA

Aerosoft PANC

Razi2Gate VHHH

OrbX Global

Navigraph Simlink

PTA 

If I were you, I would re-attempt the flight with all addon scenery and add-ons disabled (Orbx Global is ok as it only replaces the default textures). If it works, you re-attemp your next few flights with more scenery/add-ons enabled again.This is to Identify and eliminate the culprit (if it is a scenery/add-on). 

From experience, ntdll.dll typically points to a corrupt nvidia driver.

By any chance, did it crash in the vicinity of Labrador/Newfoundland, and do you use GSX? 

If so, on your next attempt, click disable GSX once you reach top of climb, (via the addon-on menu). Once you are approaching KBOS re-enable GSX.

There has been lengthy discussions in the Avsim P3D forum regarding the Labrador/Newfoundland area, interacting and triggering GSX and ultimately FSX/P3D to crash.

Best guess is faulty default facility data, or something much deeper within the ESP/Simconnect code. 

Somehow disabling/re-enabling GSX, or re-starting countl once and in-flight helps prevent the issue entirely.

I was away from my PC at the time it happened, but given the timeframe, yeah I probably was around that area. I’ll set up the exact same flight today and disable GSX. Thanks for the tip!

There was an update to GSX last month or so that addressed this problem.  Simply put, GSX is now disabled above 250/10000.  If you get a response from GSX above than then you need to run the FSDT Updater.

I haven’t updated GSX in a bit, so that makes sense. I’ll get that done right now. Thank you

I just had the same CTD over that area earlier today.  Thx for the GSX heads up, but mine is also updated.

Just landed after 8:25 hours flight, KPAE-ENGM. No problem.

Updated -400 like advised, then installed -800. Active Sky and Cloud Art in use, no GSX.

DD's Seattle Airports, Aerosoft ENGM. ORBX Vector, LC and textures and ORBX NOR package. 🤘

[acamp04]

Sounds like it could be a GSX problem. I'll try my flight again with it disabled and report back.
