Nope, crash is a random event. I usually crash at least twice a day. But my guildmate will request his place on Guiness for crashing at least 10 times an hour. According to someone that answered the same question for me, this is a poor programing fault. I really don't know it this is true, but you gotta wonder.
Well thats not to say that ALL crashing is because of that issue, just that some of the crashing is. It seems to me that, being built on such a poorly maintained engine, trying to load 40+ players along with all the out of date textures would easily cause a crash in the games iniquitous resource allocation
