To me the problem seems to occur more often when an admin has joined the server. As soon as one admin joined the game crashed and I wasn't able to rejoin again (kept crashing on connect). As soon as the admin left I had no problems rejoining (arma3_2014-02-09_12-51-14.zip).

As soon as admin joined, 6 people crashed (arma3_2014-02-09_15-34-52.rar)
