I can confirm this. We (WOG) have same problem. All clients crashing, but server working fine. Dump: https://dl.dropboxusercontent.com/u/63447803/Arma%2B3%2Bbidmp.rar

This happens on other servers, and without addons. After the upgrade, 1.28, 20-30 minutes ArmA2 bug
All made in both directions http://feedback.arma3.com/how-to-user.html
It does not help.

Same for Arma 3 dedicated Linux server with 4-10 players:
Server keeps running, Clients crash (all clients connected to that single server at once).
Happens regularly every 20-30 min.

Hi, I'm Admin with Pearl84 on the same server.
I've uploaded the files from a crash just happened on our test server. I was alone on the server.

Thank for your help

Thank you for the files. Could you please try to specify when these crashes occur? Is it any moment common for the crashes? Also, which missions are your servers running (and the crashes are happening during them)?

It seems to happen in a random way after patch 1.28, on our official server we're running Altis Life 3.1.3 and we've noticed that with less than 20-30 players it occours only to few people (3-4 a times) but if we are over 30-40 players it can occour from 3-4 to 20-30 people at the same time.
On the test server we're running Altis Life 3.1.4.6 and only tested with 3-4 people. As said by Pojus before, today with only him online (and afk doing nothing) the crash occourred.
At the moment we haven't found a common cause for these crashes

looks like its a BEClient.dll related crash, I've been getting these as well. Usually after 30 or 40 minutes of gameplay (of course this happens after the netcode seems to break, certain actions with vehicle (Get in and get out), end up not being sent to everyone else on the server). The problem probably isn't visual in any way. It's something that is going on "under the hood" with BE.

yes, I can confirm that the crash is connected to Batleye libraries. We are investigating it and can already reproduce it.

Thank for your help Iceman. I await your response.

Any news about this issue? Otherwise my whole community needs to patch back to legacy build.

Hello,
these crashes are unfortunately known issue for 1.28 Stable version. I am closing this ticket as duplicate, please keep track of the linked original one.

Ok, thank you Iceman. I follow the original ticket.
