Re: Tomcat freezes up

[Sebastiaan van Erk]

It seems very unlikely to me that the problem is in the Tomcat code. It is very widely deployed and any deadlocks would be found relatively quickly unless you use a very obscure setup.

Did you do any standard deadlock debugging? E.g., thread dumps and deadlock analysis when the freeze occurs, debug in eclipse with the sysdeo plugin and examine the state of your application when the freeze occurs... etc. Note that reporting a bug is not very useful when there is no information on how to reproduce the bug, you'll just get a WORKSFORME or NEEDINFO status on the bug.

I posted the same question week back. People advised me to handle the
resource safely, like freeing up the database connections after use,
releasing file handles etc. I am very sure that I am doing that perfectly,
but still my tomcat freezes over long run. I've seen this case in many
instances. Is it an issue with tomcat thread handling? Because, in user
applications, these freezing problems happen most of the time, because of
poor thread handling.

Better we enter a bug/ discuss this issue in tomcat developers forum.
