Mustang Posted January 30, 2014 Posted January 30, 2014 This could be the reason a particular training mission we have crashes all the time. I uploaded the tracks a while ago. In this mission the aircrafts respawn in the air (no take off) and they fight in air to air scenarios. Eventually the clients will eject/crash/respawn many times and we use to crash at around 40 minutes. Exactly, i was trying to push this scenario of crash across to ED before the end of last year but was unsuccessful.
m9matt Posted January 30, 2014 Posted January 30, 2014 The crash is reproducable in a very simple mission (no AI or weapons) with just a host and 2 clients both airstart and nothing else - just keep crashing into the ground and respawning over and over and eventually the host will crash (clients get a ping timeout) i'd like to see if anyone else could reproduce this. Interesting! So after so many crashes and respawning, the server will crash ? I wonder how many times it takes before it brings down a server ?

I wonder how many times it takes before it brings down a server ? Try it! just host a simple mission like i said, all airstart with no weapons or AI/objects and ask clients to just keep crashing over and over into the ground, see what happens (it may take a few minutes to cause it but i think with many clients it can be done quickly) Edited January 30, 2014 by Mustang

Just A10C, F15C, Huey and P51D. I then joined my server from a different pc. There were no changes/additions to the mission, all pure client slots. Then just kept crashing, by myself. One person looked into the server, but decided against this crazy mission. I must admit, I did think it was a bit crazy. But I did have the first A10c very close to a mountain. Then I tried an F15 slot, and then back to the A10c. It took me 10 minutes to crash the server !!server-20140130-210707.trk 1

Perfect, now the ED devs need to try to replicate the same crash on the internal build they use and hopefully we'll be getting somewhere :)
Pilotasso Posted January 30, 2014 Posted January 30, 2014 Aircraft debris have always caused trouble in multiplayer missions. Servers crash may be a more virulent manifestation of the same evil that plagued the sim since lockon times. .
TAW_Blaze Posted January 30, 2014 Posted January 30, 2014 Interesting find Mustang. Good luck getting it to ED!
RedRain Posted January 30, 2014 Posted January 30, 2014 Seriously, do we really need all this eyecandy, advanced animations, smoke, debris, explosions, etc etc. is this product not supposed to be a flight/combat simulator ? Since owning this product I have learnt more about computers than flight & combat. Leave all the eyecandy to the arcade games, and let's get back to the fundamental basics, flight & combat simulation. Optimism is waning.
ENO Posted January 31, 2014 Posted January 31, 2014 Yes- who needs smoke, explosions and debris in a combat simulator? I'd be interested in seeing the dcs log / crash file after that crash... See if there are similar signs and symptoms to some of ours. Now that you mention it, many of our crashes occur near a point in a variety of missions where more people are shot down... That's when the weird artifact etc occurs which gradually leads to a server crash. Relation / causation aside- I'll go look in the crash section but if you don't have it posted could you put it up here? I'll run the same thing when I can and post findings. I'm on night shift right now so my hours are wonky. "ENO" Type in anger and you will make the greatest post you will ever regret. "Sweetest's" Military Aviation Art
Wrecking Crew Posted January 31, 2014 Posted January 31, 2014 LOL I have a mission with a nuke in it but it hasn't gone off yet. WC PS. A great combat mission has to have a good back-story. Visit the Hollo Pointe DCS World server -- an open server with a variety of COOP & H2H missions including Combined Arms. All released missions are available for free download, modification and public hosting, from my Wrecking Crew Projects site.
PondLife Posted January 31, 2014 Posted January 31, 2014 There are too many individual functional issues to count which could be causing crashes. I've yet to see someone positively ID one single issue that they can reliably recreate a crash with. I will however say that the more users on the server, the more it appears to crash and this would point towards windows session handling and the way the server handles user threads. C++ applications can have issues with memory allocation and freeing memory up if developers do not de-allocate all the memory they assign's. Having run data collectors on the s77th server and observed whats looks like a memory leak, I suspect this is the problem causing most of the instability. I get the impression ED have not quite grasped this problem, until they do, it may change a little but not much. 1
ENO Posted January 31, 2014 Posted January 31, 2014 The Firehouse will run the crash test throughout the day- I'll reload it as often as I can. It's just a bunch of slots- no weapons (well, gun only). Hopefully it'll help. "ENO" Type in anger and you will make the greatest post you will ever regret. "Sweetest's" Military Aviation Art
Mustang Posted January 31, 2014 Posted January 31, 2014 (edited) Ok ENO i was able to crash your server as the sole client, it took ALOT to trigger it (a mixture of pure crashing into ground with some occasional firing into the ground with gun before impact to get a kill messege) i reckon with more clients the crash would be triggered far sooner. edit: getting close to 160 or so deaths for one client seems extreme to trigger the crash, but after thinking about this i realize that it's not - if you spread the crash amount between 20 or more clients that averages 6-8 deaths per client, this number is easily generated on a very busy server in a short space of time.

Pman Posted January 31, 2014 Posted January 31, 2014 I may hold a crash me event on the VA server one evening next week. But it would make sense re the VA server anyway Pman

But it would make sense re the VA server anyway Pman I hope that the testers and ED devs can reproduce the deaths bug during the closed MP beta session tomorrow (fingers crossed)

gregzagk Posted January 31, 2014 Posted January 31, 2014 The same seems to occur with Combined arms ! This may be the reason missions with CA crashes a lot the servers. When CA is enable the players enter many different vehicles in a few minutes that means loading cockpits etc. I hope this could help .

ENO Posted February 1, 2014 Posted February 1, 2014 1 more try with gun at the start this time? If people gun running and crashing (never done that before personally :music_whistling: ) causes it- it makes sense. That stackhash error is very familiar.

Mustang Posted February 1, 2014 Posted February 1, 2014 (edited) Was able to trigger crash in half the time by firing gun every time into terrain before impact (just shortly after you left your last message ENO) edit: just so you know i can tell when the server has crashed just by keeping the scoreboard up while i'm flying, as soon as the deaths stop registering on the board i know the server has hung, also if there were another client present i'd be seeing him flying in a straight line till the connection interupted message kicks in (if he were in a dive he'd be semi-submerged in the ground and creating an FPS killing dust cloud, i'm sure many here have seen this before prior to a server crash) Edited February 1, 2014 by Mustang
ENO Posted February 1, 2014 Posted February 1, 2014 (edited) Sorry this one took a bit longer- dealing with some other issues too. Here are the last logs- this one looks more like a windows error that I've seen several times before (bug section for game crash.) Thanks again Mustang- it takes a special kind of person and some serious dedication to go at that single handed... Hope it helps to substantiate the need for a fix- or highlights a bug's location.
