DCS freezes or crashes

[Buzzer1977]

I already did the repair / cleanup thing, but DCS constantly crashes since the last update.
Might be the mission, because i was using the new Iraq map.
The sample mission that constantly will either freeze DCS sooner or later crash if i quit the mission and switch back to the mission editor.
The crash seems fatal, because it doesn't even write a crash dump or anything in the log.

hello. DCS is not showing a crash in the logs as you mentioned. there are lots of shader errors which may a symptom. have you looked in window event viewer for something occuring at the same time as the DCS stops working?

also share the offending mission. others can try it to see what happens.

Event viewer shows DCS two app hangs and one crash of a unknown module, which i'm pretty sure was DCS.

hello.

sorry for delay getting back. i tried your mission. i was able to load it to the point of picking the plane / client. i do not have MB339. so i quit and copied your mission to include F16 instead. i was able to load and fly.

can you run dxdiag and export the log? then post it here. 

[Buzzer1977]

It just happened again. Even without this mission by just opening the mission editor. I also included the AppHang Report file and the dxdiag.txt.
If the hang happens again i'll try to connect the debugger to the process.

i am thinking you are having a hardware error. do you have any overclocking on RAM or video card?

i see the RestService.exe process is crashing too. see if you can disable it for testing.

No overclocking on anything. All configured standard out of the box.

Seems like Incredibuild RestService.exe crashed because it was a outdated version incompatible with the most recent VS2022, so i uninstalled it.

have you tried to rename the DCS folder in Saved Games folder? make it .bak or something. then start the game and immediately exit. a new folder will be created. then you can copy the input folder from the bak folder. then restart DCS.

you also mentioned that you quit the mission and go back to mission editor. have you tried to totally exit to the main menu. then go into mission editor?

sorry i am reaching here.

Yesterday i updated my BIOS, all drivers including CPU and Chipset drivers and cleared the fault bucket.
No errors since until i did the following:
Started with a vanilla DCS folder, logged in and quit, then restarted DCS.
(I didn't copy back the old DCS files, i just restarted dcs to make sure that saving the password still worked)
Switched several times between editor and main menu. This time it hung
when creating a new mission, right after selecting the map and coalitions.

Update: I ran a memory test and it couldn't find any problems

nullI attached the profiler from VisualStudio. It seems some times it just freezes for some time. Some times long enough to cause the hang.

have you tried to install or reinstall the Microsoft Visual C++ Redistributable. there are two in the DCS folder. though i have seen people suggest installing the latest.

[Buzzer1977]

Installed latest MSVC++, but it didn't change a thing.
I've got the feeling it has something to do with file IO.

Found out: It seems related to my Windows profile, because i've got some network drives mapped that are not always available. The question is: Why isn't other software affected? What does DCS differently when scanning the directory structure?

good question. i personally had an issue many moons ago with the slideshow for windows desktop. you know where you can pick anywhere to call the images and it changes at intervals? that was causing stutters. disk reads are a real problem with DCS. i do not do anything such as this when DCS is running. so makes sense but does not explain why DCS chokes. DCS is like a beautiful but crazy girlfriend.

[Buzzer1977]

nullI attached the process monitor. Seems like DCS is doing a gazillion of unnecessary, redundant IO requests.
Multiplied by the slower response from the OS due to the network drives this accumulates to the hangs.

I've added the zipped procmon log for DCS.exe during the hang.

nullMost time seems to get lost with numerous "Create-QueryNetworkOpenInformationFile-Close" cycles.
