You can also activate server logs to log both visitor and bot activity by configuring AccessLogValve : http://tomcat.apache.org/tomcat-5.0-doc/config/valve.html .
Some bots take up a lot of sessions, you can verfiy this by running a program like Xenu Link Sleuth on your site. Then, you will be able to block certain bots by IP address or User Agent string. -Rashmi ----- Original Message ---- From: David Wall <[EMAIL PROTECTED]> To: Tomcat Users List <users@tomcat.apache.org> Sent: Tuesday, February 6, 2007 1:54:52 PM Subject: Re: Large number of active sessions It seems that Tomcat 5.5.17 (and earlier) has had some sort of problem in timing out sessions. I'm not sure if it would clean itself up if the person really came back and did another HTTP transaction or not, but I've noted that Tomcat Manager will show sessions that are have been idle much longer than the session timeout value (based on the "last access timestamp" in the session). Our application also has a registered listener HttpSessionListener and we've seen that these old sessions do not trigger that callback either as we also list the session as active. As for suggestion (1), this won't matter and 30 minutes is the default. As for suggestion (4), this could clearly create extra sessions for those few who don't allow session cookies, but even those sessions should time out.
