I don't know what that principle is.

Ok. Then you're not sharing a shibd process or trying to cluster the SP 
itself, which is a major piece of information. So there shouldn't be *any* 
shared state between the machines that's relevant to the SP, and if there 
is, you should stop that and see what happens.

Well, at the end of the day, the only way to deal with a crash is to debug 
it or get a stack trace.
