The same issue as markusua posted.
I think this is new (1.214) battleye client related.
Yesterday my linux server was running on:
Arma 2: Operation Arrowhead betapatch v1.63.112555 from __https://community.bistudio.com/wiki/Arma_Dedicated_Server#Linux_2
Battleye Server v1.185 from battleye.com
My Battleye client version was 1.208. Arma2 OA client version 112555. My OS is Windows x64.
I was in game and after battley client updated from 1.208 to 1.214 my game crashed to desktop. I login through rcon and see that all players on server began to have problems with connectivity:
Player xxx kicked off by BattlEye: Client not responding
Player xxx disconnected.
Player yyy kicked off by BattlEye: Client not responding
Player yyy disconnected.
Player zzz kicked off by BattlEye: Client not responding
Player zzz disconnected.
I login through ssh to server, check network and everything was normal with internet connection:
I open logs and discover only new phrase in logs:
Player xxx is losing connection
Player xxx kicked off by BattlEye: Client not responding
Player xxx disconnected.
I tried three more times to go in game and everytime after 1-2 minutes in game the arma oa.exe crashed to desktop.
This was on v1.185 battley server.
I restarted arma oa server and discover that now it running with 1.190 battleye server.
I tried to dive in game, but arma oa still have issue with crash to desktop.
Rcon says me that all players on server have problem with clients: "Client not responding"
I redownload BEClient.dll v1.214 from battleye.com and put it in Expansion/Battleye folder on my game client, but it not helps. The same issue: Client not responding
Then I turned off battleye server in server.cfg and gaming 2 hours without any problems.
I think that BEClient.dll v1.214 have problems with connectivity to linux version of dedicated server Arma 2: Operation Arrowhead v1.63.112555.
Sorry for my english.
