hi, Sorry for reposting, cause i keep getting message not delivered...
For your questions, top shows cpu around 40%, actually we have trace our cpu usage for the week, it peak at 50% and average 30%. For memory, it peak at 60%, average 25%. No, the database is in another server thru a firewall. Initally, we suspect the connection not closed properly, but after we enable the 'removeAbandoned' and 'logAbandoned' and check all connections are closed, tomcat still hangs. Debug level set to '0'. innovest --- Parsons Technical Services <[EMAIL PROTECTED]> wrote: > What does top show? > Is the cpu loaded? > Is the memory maxed? > Is the database on the same machine? > > When you say hang it can have many meanings.
