See previous such questions in the archives. You have to take three thread dumps with small interval between them, to see what Tomcat is actually doing. (How to make dumps -> see FAQ). One usual cause is when you have infinite timeout on you database connection pool. So threads are waiting for your DB. (If you are not recycling sql objects properly, you may run out of them easily).
