SQLEXception: The Connection is closed

Hello,

Recently I got the LiveCycle Server environment built on Windows 2003 Server, JBoss 4.0.3 SP1 and MS SQL Server 2005.

This is a production server, and will be used sometime next week. I have this server UP for the past few days, though there is no activity on the server, I am seeing some exception logs in the JBOSS server.logs

I am not sure whether this execption occured because there is no activity on the server, or there is something I need to worry.

Please help me in this regard.

Thanks in advance
Sivajee.

Here is the trace of the exception logs:
