My first lock happened after just moving within sight of Novodtromovitsk (sp). I had just finished looting the train station on the southern hill. I had used a damaged can opener to open a can of beans. I began eating them. During the eating animation, the red connection message appeared and i was kicked from game. I can't recall if the server i was playing on went down or not, though I remember thinking it may have been down. This lock was the longest, lasting approximately 17 minutes. When i finally saw the lock removed and was able to get back into game, my can of beans was in my inventory, unopened.

not sure if this is helpful, but heres a post mortem. i was able to get back on again about 20 min after my last comment. It happened the same way, i tried to join a full server and got the queue message. it said i was number 2. then i waited till i was kicked. believe it was for losing connection. the next server i tried to join, i was in. i played for a few hours before finally getting the red lost connection message again. that happened after running through nw airfield. it happened in the field soutwest of the airfield while i was sitting under a tree.

well, i'm locked again now. same thign as before. this time i wasnt eating, but running through the aforementioned town with random guy i bumped into.

I'm back in as of right now! not sure what i did. i got a waiting in queue on one server, then kicked cuz i lost connection. then tried again, saw locked msg, then suddenly the loading screen popped. my can of beans was in my hands unopened.
