CTD upon touchdown

[Viking01 181]

Don't know if it helps, but I just found this crash report about yesterdays crash. Don't know why I didn't find it yesterday...

Once again I revisited my all-time CTD scenario and as always I got what I asked for.

Drzewiecki Design's new La Guardia airport, stand  H10. GSX pushback, AFE fully utilized, taxi on Y towards RWY 04, crashed approaching the runway on twy Y. No error message, just a momentary freeze followed by the program quitting.

What I find interesting is that I always, consistently use the exact same procedures for departure. AFE, GSX, same aircraft equipment and setup, same settings, same ramp manager items yet I do not crash to desktop at all airports.

So far, only La Guardia, Minneapolis, Denver and Washington Dulles (the first being a product of Drzewiecki Design and the latter three ar Flightbeam products). Therefore I believe it could be something specific to these, perhaps one of more of their components interfering with the DC-6 in some ways.

First time ever for me, a crash at a non-SODE airport. It is FSDT's Vancouver this time. Again, pushed back - using the P3D default built-in push back command, and then started taxiing. Less than 30 seconds later, the usual momentary freeze. This  time a series of logs were created and below I pasted them from Event Viewer.

In this case, FSDTs COUATL engine caused the crash

In this case it appears so. And also, most of my crashes occurred at airports that have something to do with Couatl. But not all. Drzewiecki's KLGA has nothing to do with Couatl yet I crash to desktop 100% of the time. Also, I have not experienced any issues at FSDT's other airports.

However, the nature of this latest crash is excatly the same as my other crashes and if this one was caused by Couatl then it is possible that all of my crashes are because of Couatl. I am gonna completely disable Couatl and test Drzewiecki's KLGA once again and see if I crash or not. Unfortunately there is no way I can test FDST airports with Couatl disabled - that would disable the airport itself. 

Nevertheless if I don't get a crash at KLGA with Couatl disabled then it's worth looking deeper into. Will report back.

Maybe once you've done that, also ensure that couatl is up to date by running FSDTs live updater.

It is certainly fully up to date. However for my tests I now disabled Live Update.

I too have been experiencing CTDs but never on touchdown, always when taxiing.  I have also narrowed it down to the following conditions

Always at night, always in the DC-6, and always when I begin to throttle back.  So for instance I keep my RPM at 1500 while taxiing, but now I'm coming up to a turn, so I reduce throttle to reduce speed.  As soon as I begin to pull back I get a freeze for a few seconds and then I get dumped to my desktop with no message at all.  My dc-6 log has no mention of any errors, and Event viewer is empty following my latest crash.  Also, once the CTD happens, I can load p3d right back up and go through the same exact scenario and every time it works fine.

Do you have GSX or any FSDT products installed? With the exception of one crash upon touchdown, the other dozens occurred after started to taxi. However, it's totally random, day or night. Can happen at anytime. Also if you click on the screen when the few second freeze happens, you will trigger an error message which will also leave a log in Event Viewer.

Question for all: what hardware (throttles/joystick/yoke/rudder) are you using?

[Jack_Sawyer 4,600]

Saitek yoke, 2 Satiek throttle quads, Saitek rudder pedals.

 

[kityatyi 78]

Saitek yoke, Thrustmaster T-Flight Hotas X throttle, Thrustmaster T-flight pedals. 

I have not had a single crash since I disabled FSDT's Live Update and GSX. Approximately 10 flights in a row with no issues. Promising but can be pure luck too.

Similar to Jack - Saitek X-52 Pro throttle & stick, Saitek rudder pedals.

At least one of my CTDs for certain was when I happened to touch the pedals during taxiing - having used only the twist grip to steer (set up as a tiller) up to that point. It's possible that the operation could have [also] triggered a sound event (like tyre or brake squeal) but I wasn't aware of hearing anything in that split-second before the CTD.

I have to say that (IMHO) Saitek drivers are some of the most appalling pieces of software I've ever encountered - so I wouldn't be at all surprised if there's some incompatibility issue there.

You could do the flight sim world a huge favour by employing your undeniably brilliant coding skills in writing some decent drivers and giving them to Saitek, LOL! A piece of cake, I'd have thought, considering what you've achieved in with the NGX!

Don't believe HW has to do anything with it. I am using CH pedals, throttle quadrant and yoke. Up to now I had only one CTD during taxi
