Hi All,

I have an application which is running in Tomcat 5.5. It is developed with the heavy use of Spring/Hibernate. It runs well for 1-2 hrs but then just hangs. Tomcat does not show any error (out of memory or some other) in the logs but does not respond to any request. I can only see the app's login page once it hangs.

In my application, a set of 10 jobs (Quartz API) get fired after every 5 minutes. I checked the logs and these jobs tohether take just 3 seconds to finish when the server is running normally. I have checked my code many a times but I doubt its my code's problem.

I have also tried increasing the heap size but it did not help either.

I am really confused as to what can be the issue. Is it some problem with Spring/Hibernate configuration, Memory leaks?

Please suggest me how can i really diagnose the problem and fix it.

Cheers,
Nitin

P.S. I am duplicating this post in this forum as well since I am looking for this solution really fast.

Please do not cross-post the same question in multiple forums. It wastes people's time when multiple redundant conversations take place. Please read this for more information.
 
It is sorta covered in the JavaRanch Style Guide.
