Thank you David for showing special interest in MP issues. Let me start adding my MP issues as I revisit them:

http://feedback.arma3.com/view.php?id=14517 //MPRespawn is broken, security issues with global effect of MP EHs

http://feedback.arma3.com/view.php?id=15388 //When date is changed on the server, the synced date's year on client is stuck on 2035

(the last one was marked as resolved)

Edit: preInit ticket was also marked as resolved now (nothing will change).
(It's sad to see that there is no real interest in MP @BI :(
I'm bailing out here again, not worth it)

http://feedback.arma3.com/view.php?id=12433 //various inconsistencies with inventory commands (see spreadsheet)

Dunno if we are supposed to include feature requests here, but here it is anyway

http://feedback.arma3.com/view.php?id=13784 //streamline server joining process

Can anybody test if the following is still valid:
https://dev-heaven.net/issues/25053
and if so create a new A3 ticket?

(No access to my PC currently)

The larger issue is that there is no multiplayer except for a handful of small coops. Relying on content from the community (which are often times, buggy, broken, no longer compatible, unsupported and / or works in progress) leaves multiplayer aspect of A3 empty and dying.

The current crop of gametypes and missions are largely revisions to A2 missions.

Additionally the server browser is broken and reports inaccurate numbers of servers, types and players.

Top quality MP missions and gametypes should have been on the drawing board months if not years ago and should be officially coded, tested, and maintained over the life of the game. Yes this takes time, money and resources but if A3 is a game and not just a game engine then you actually need to provide some large scale multiplayer, p vs p, content here.

All the same... server run hit 2GB RAM and crash... or crash because he want it... very silly...
