This suggests that Tomcat and the VM are okay, but your webapp is hosed. Do you use JDBC connections in your application? If you do, do you pool those connections? If you have exhausted your connection pool, your threads will wait forever for a connection (depending on your CP settings). Chuck's suggestion to obtain a thread dump will be very helpful in determining what's going on. Look through your thread dump for Object.wait() before just dumping the entire thing to the list. -chris
