Apologies if this is an obvious question, but have you checked that the applications deployed on your server have no memory leaks? A memory leak can well be the cause for an OutOfMemoryError, and upping the amount of memory reserved will just delay the death but not prevent it. Actually fixing the application defect can result in being able to run the server with significantly smaller amount of memory. -- ..Juha --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
