Was running FRAPS all last night and no crashes. Did you check memory logs?
Its was just the usual:

However I looked at the after game report and it would appear about 20 people didn't finish the game (i.e. each team had 42 players overall, meaning about 10 on each time quit or crashed out) so maybe that server was dodgy. I find it hard to believe 20 people actually chose to quit mid game like that. Some of them had really good scores. When looking at all previous reports for games I haven't crashed in, only a couple players were listed as not finishing the game.
Went back to one of my known good servers in favourites ( i.e. one I have never crashed on) and played a whole round of SOS without issue.
