Using tabbed browsers causes session sharing
Hello All While using tabbed browsers (e.g. IE 7) I am facing a login problem. Say on Tab#1 I login with a username A, on Tab#2 I login with username B, I still see A's session. Apparently the browser/Tomcat doesn't create a new session. Has anyone faced this problem? Are there any fixes? Thanks Murthy
Why does Tomcat become slow during weekends?
We have a website based on embedded Tomcat with Jboss 4.0.2. We noticed that every weekend the Tomcat becomes sluggish. I mean there are no errors like HTTP404. The website simply hangs. We theorized that JVM is busy with garbage collection. Is that realistic? Does anyone have any other suggestions? Thanks Murthy - Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

We noticed that every weekend the Tomcat becomes sluggish. Backups? Congestion on the network due to a site that's only accessed heavily at weekends? There are no backups. The website uses DB2 which is backed up infrequently. And all of our users use the site during business hours on weekdays. We theorized that JVM is busy with garbage collection. Is that realistic? No. The JVM collects garbage at intervals measured in seconds or minutes, and takes milliseconds or seconds. It also doesn't know about weekends :-). I forgot to mention that there is an apache/mod-jk load balancer in the front end. On weekends we end up restarting everything including apache and jboss. Does anyone have any other suggestions? I'd guess system maintenance of some kind. Is this on a physical server or a virtual one? There is no other system maintenance more than what I have mentioned. The Tomcat runs on a physical server. Heard a virtual server will be even slower. - Peter Thanks Murthy - Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.

D This seems likely as we have seen some problems with DB connections. I am not sure how to keep the DB connections alive when there is no traffic on the website.
