Error : Runnable did not complete within 10000ms

[piyushgpt1]

My company has a web application running on JBoss-2.4.4_Tomcat-4.0.1. It works fine for a few days, but once or twice in a week, getting the exception :- Error : Runnable did not complete within 10000ms.

I need to provide an answer as why this is happening. It happens one or twice evrryweek, I restart the server and the problem gets resolved. Please help.

When I see the nohup.out file, the detailed error message is as:-

Go over the code and find out what is causing these things,

- Check the number of connection your database allows
- If your application is using connections manually and not releasing it
- If possible monitor the database server for few days
- Change the log level to TRACE
