Thanks for all the help guys, I think I found the problem. It appears that after a delay the next attempt to access the database to sign on with the SingleSignOn valve, using a JDBCRealm, throws SocketExceptions about a Broken pipe. I think my firewall is resetting the connection when it does not detect any traffic after 3 hours. I am looking into how long I should make the timeout, suggestions?
The thread kill and the gc statements helped a lot and I am sure will come in handy in the future, I opened another thread about why DBCP is not used for SingleSignOn, check it out if you are interested.

BTW, have GC statistics now being dumped. Hopefully that with the logs and the thread dump will lead me to the problem.

BTW, any ideas on how to get a thread dump of the JVM on Linux? I am definitely not out of memory but I will modify CATLINA_OPTS to dump the GC statistics. Please check back tomorrow after I have a day of logs.

It doesn't give me any kind of error, : the browser just continues to process the request without ever timing out. : Any ideas? A couple. A situation as generic as, "never responds" gets generic advice: 1/ Check a thread dump of the JVM (search the archives if you don't know how), see whether something's deadlocked. Slim chance, but worth a shot. 2/ Check memory usage and GC, perhaps use a profiler. GC can make an app appear several shades of unresponsive. 3/ check the logs : 2] Tomcat manager does NOT delete my .war file on undeploy, I don't know about this one, so I'll leave it for someone who does. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
