Your web application has a memory and/or resource leak. Run a profiler to see what code is not releasing references to objects, closing files, etc., ....

Given you've already said this happens overnight, you might want to start your analysis with the background process you have running.

Hello Tomcat Users,

When our web application runs overnight on Tomcat 5.0.19 we get the following error. I searched on the Tomcat Users and Developers Mailing list archives on nabble but
did not find any mention of this problem.

Anyone seen this before ?
