Hi Mark,
thanks for your reply.

My linux boxes have 4GB RAM available and there is no trace about a out 
of memory error. In fact, i run 7 tomcats instances on different ports 
on the same machine. However it is always the same one who disappears 
... quite weird. I can't see anything in /var/log/messages nor 
catalina.out indeed.

Any other clue? :S

Thanks for your reply. I really appreciate. :)
