fixed Frequent Crashing when being killed in an Mi-8

[FusRoPotato]

Title says it all. I've been crashing to desktop without message very consistently +80% of the time during death while inside an Mi-8 (and so has a friend of mine). Doesn't appear to matter what the initiator killer is. It can even be death by crashing into the ground. It will just send us to desktop without warning.

This is after a slow repair, no custom files, in a multiplayer server, and happens in both MT and ST.

These are the last lines of my log. No crash or track files are being created.

Hi. I tried this before in SP but couldn't replicate. Is that MP-only?

[FusRoPotato]

I haven't received a CTD in SinglePlayer yet, but I haven't done much testing there. Maybe only 3 deaths total in SP.

I've crashed about 15 times in MultiPlayer from about 20 deaths. Rough guess without logs. Not all deaths and helicopter destructions resulted in a CTD, but I've been through as many deaths on several other modules without CTD so I assume there must be something special about the Mi-8.

I don't know how to capture more information on the event, but if I did, I could probably replicate it again easily.

[Flappie]

OK. I'll give it a try.

[Flappie]

I hit the ground 10 times in a Mi-8 on my dedi: no CTD.

Well thanks for trying. There must be something particular about my server/mission that is causing some of us to crash, but only when dying in that specific helicopter. 

It has happened without other players present and I have been replicating this problem on the Marianas Map with a cold-start aircraft. I'd have to do a bunch of testing on Caucasus to see if I get away with it but unluckily, I am suddenly away and short on time. I will try to investigate Caucasus this weekend. 

There are super carriers, AI ground units, A2A units in combat, AWACS, boats moving around, and drones flying in the server. Often plenty of munitions craters and crashed vehicles littered about. If you'd like to check it out, it's a Marianas sever with Darkmatter in the name. It's possible there could be an issue with smoke effects, decals, or other possible impactors on ram or vram that may be contributing to the trigger, but I've had a few crashes on death while playing alone on a fresh map which suggests it doesn't take too much activity if activity is contains the trigger.

Did you run with hot starts or already flying starts?

Air starts.

I'll try to visit your server tomorrow and have a few crashes with an Mi-8.

[FusRoPotato]

Thanks, I threw in an air start and hot start just to test it but haven't had a CTD when dying with either of those yet. If I can figure out something consistent, I'll make a track file copying all my actions before death.

[FusRoPotato]

Update:

4 airstart attempts, no crash

2 ground hot attempts, no crash

2 cold attempts, 2 crash

1 hot attempt, no crash

2nd hot attempt trying to iteratively change switches around to isolate condition, all heater switches to the right of external lights on, ->crash with crash report and a track that lead to the crash this time, although replaying this track doesn't appear to cause a crash itself.dcs.20230321-053138.trk

I'm not sure if this is going to be the same crash though because this is the first time it asked me if I wanted to submit a report

with your track replay above I see a crash in open beta. 

Good news is our internal version does not see a crash, so its possible this is already fixed and will be in the next patch. 

thank you

 

[MoleUK]

Incase it's needed as I just had a CTD in the mi8 on death:

I'm going to warn you, I have replayed this track many times and it only crashes half the time. It's possible it's not fixed. Somehow this crash is a diceroll on a track replay. Hopefully that is a clue to someone.

Haven't had a crash yet, many vrs deaths later it seems fixed.

Two crashes today in hip, both on impact with ground.

thanks we will take a look

If anyone is still seeing this crash after the latest DCS Open beta 2.8.4.38947 please let me know 

thanks

[Torque]

Unfortunately, I still have the same issue even after the last update DCS Open beta 2.8.4.38947 on Steam.
Crash to desktop when killed in Mi-8.

I haven't given it another whorl yet, but I can vouch for a few friends I've seen CTD while dying in them.

[Torque]

It’s seems to be ok now!  

So far so good, I tested it on the mission editor and air + cold start no crash to desktop when killed. 
I used the same version DCS Steam Multi thread : 2.8.4.38947

The only thing that I changed is my Multiplayer password. 

[FusRoPotato]

There are several of us still experiencing a CTD when dying in the Mi-8.

[Badger1-1]

Dont have a record of it but it happens everytime in MP when I get shot at by Vulcan or Gepard(dont think it matters) my DCS crashes.

 

When shot at by other Aircraft this does not happen, also minimal damage does not trigger the crash but only if you get hit more severely.

 

Since it always crashes I cant say what system were hit. 

[Flappie]

Hi. You're not alone with this issue, but so far no tester could replicate this crash. Please attach the latest zip file from your "Saved Games/DCS.../Logs" folder.

[Badger1-1]

My logs dont show a zip for that date just these:dcs.log

 

i think it only triggers when youre hit from the side. 

Edited April 26, 2023 by Badger1-1

[Flappie]

Thank you. I don't see any lead in the log. I'll give it another go, specifically with Vulcan and Guepard shooting at the side oh the Mi-8.

@Flappie

Getting this A LOT on Enigma CWS.  Pilot dies, DCS crash, pilot crash lands (survives) DCS is fine.  Will attach logs next time it happens.
