Yep, that's it. > When the problem occurs, is the entire JVM gone or is it still running > (meaning that only the current thread could be having problems)? > Also, have you tried activating DEBUG (say level 3) to see if you can > get anything useful?

I wanted to avoid the DEBUG 3 in production since it slows it down... but that may be irrelavent if it's not working right :) -- Michael Peters Developer Plus Three, LP
