DCS 1.5.5.58891 Crashing (Mission Specific?)

[pdmarsh]

DCS 1.5.5.58891 has been crashing at roughly the same point, although not the exact point, in this particular mission. This does lead me to think my problem might be a corrupted mission file, or someting along those lines, but perhaps it is DCS related. I haven't flown other missions in 1.5 recently, so it's tough to say. I am not seeing other error messages, e.g. GPU related.

 

A characteristic of the crash is that DCS goes to a black screen with the logo appearing, but I can hear the mission continuing in the background. After a few moments, the "DCS has stopped working" message appears.

 

The log and crash files, along with the mission itself, are in the attached zip file. Any review of the log files and comments or suggestions will be appreciated.

 

Thank you,

Paul

Recreated Mission Still Causes DCS to Crash

 

I was fairly certain that I had a corrupt mission file, so I recreated this mission from scratch. It still causes DCS to crash as noted above. In this case it got slightly further along, but still crashed at roughly the same place in the mission. Either I am doing something illegal in how I'm setting up my mission, or I have uncovered a bug. I have attached new log files along with the recreated mission file.

 

It's pure speculation, but I suspect the problem might be in how I am using the JTAC aircraft. I noted in an earlier post that attempting to assign more than four priority targets breaks JTAC, but that did not cause DCS to crash. JTAC simply did not show up as a resource in-game. My workaround was to create a list of triggered actions in the JTAC aircraft setup (Engage Group) and then use a trigger to begin working through the list. The crashes always occur near the end of this list of 9 targets, i.e. after I have destroyed 7 or 8. One of the 9 targets is on late activation. I put this one at the top of the list in the trigger since I want JTAC to assign it ahead of others should it activate before all of the 8 other targets are destroyed. I tested this and it worked great, but I never tried going through all 8 targets first.

 

I'll look forward to any feedback on what is found in the log files should anyone have a look.

 

Thanks,

I did more testing and can say that the problem is indeed related to JTAC. However, I don't know specifically what it is about the way I have JTAC set up that is causing the problem. I first removed the ninth target from the triggered action list that was on late generation. I was able to get through all 8 initial targets and was landing at a base to rearm when DCS crashed. I then removed all triggered actions from the JTAC setup and deleted the trigger that would have initiated those actions. I was able to complete the mission without DCS crashing.

 

There is a bug related to JTAC and/or triggered actions. I hope the log files help point to the underlying problem.

Thanks for the logs, I will try see if I can see the issue, but it is never easy :)

 

Edit

 

try a fresh install of your graphics driver, the logs show your card is removed. Let us know if it helps

 

02962.617 ERROR DX11BACKEND: failed to create vertex buffer. Reason: DXGI_ERROR_DEVICE_REMOVED

Thanks Bignewy. I appreciate the time and the help. Interesting about the graphics card. I will reinstall the driver as you suggest.

 

I noticed some other odd JTAC behavior. When it gives you your target it calls out other threats in the area. It seems to be calling out nonexistent threats. The counts it gives for some can't be accurate. Oh well, that's a problem for another day!

 

Thanks again,

Paul

no worries,

 

do you have a mission where it shows the issue, if I get enough time I can try to reproduce

Both of the missions in the zip files show the problem. Unfortunately, it takes a good 30 minutes or so to get to the crash point. You work through the JTAC assigned targets and the crash occurs toward the end of the list.

 

I would suggest using the original mission, which is V3 and in the first zip file that I attached (Logs.zip). It seems to cause the crash a bit sooner than the remade mission (V4).

 

Thanks,

@Bignewy -- If you do fly the mission, you will be given primary target coordinates at the start. Do NOT attack that target until you work through the JTAC assigned targets first. When flying this mission as a single player, I take out all of the threats first. This leads to the DCS crash. If you get through all targets and JTAC says no further tasking available, RTB and rearm. I you actually get that far, chances are you will not be able to reproduce the DCS crash. It has always occurred before that point for me, and every time I try.

 

Thanks,

Paul
