l4d server in a mode versus
After updating sourcemod to the version 1.2.0-hg2453 there was a bug: in the end of mission the airport when all players automatically leave from a server, on a map bot survived, zombies and tank respawn. Survived and the tank are immortal. The server cannot replace a map. At manual change of a map - server to crush.

I experienced something that sounds similar to what happened to you, only without a crash. I was using build 2441. I wasn't sure if it was SM's fault or not and it only happened once.

What happened to me was at the end of the game, everyone but me got returned to the lobby. I was left in game and it switched the teams again as if it were a third round on that map and the game acted very strangely (zombies kept streaming in targetting me instead of being spawned around waiting, when I got up to the top I couldn't hit the radio, a little while later the chopper showed up anyway and I got in). Then it switched me again to infected and filled the other side with bots, but all I had was a blank screen. After I left the server, we couldn't join again using sv_search_key until I restarted it. I tried manually changing maps, checking the master servers, and sending a heartbeat before that.
