java.sql.SQLException: Io exception: Connection reset

Hi

I would like to know what causes to get below error:

"java.sql.SQLException: Io exception: Connection reset"

We have webapplication deployed on Iplanet6.0.

Wen we deploy for 1st time it works fine.

After 1 hours application is not accessible b'cas of 'coonection reset'problem.

If we restart web server then it behaves normlly.

Note : we are using struts data source.

Any ideas.....!!!!!!!!

Thanks in advance.

It's not clear how your application using DB connection. Does your app use WS database resource settings?BTW, WS6.0 is EOLed. Please use WS6.1SP6 or WS7.0 preview for your application. IF you still see the problem, please provide more detail info. like server.xml settings.
