Hello,
We have faced an issue with production
JBoss server. Server stopped responding for almost 10 minutes and returned back to normal state after it. During this interval clients were not able to connect and no error or warning messages were logged to log files. However we have an known and open bug in the deployed application. One connection is not closed and Resultset and Statement is also open on this connection, could this be cause of this problem ? Same application is deployed on other three JBoss server but none of these server had this issue, though waring "Closing a connection for you" is being logged frequently on all the four servers. Datasource is configured in mssql-ds.xml as non transactional DS. How JBoss Handles open resources or its Database Driver's call to handle the open resources? Here are the Environment and server details.
Environment Details :
Os : Linux 2.6.18-194.17.4.el5 (i386) CPU : 1
JVM Name :
Java HotSpot(TM) Server VM
JVM version : 1.5.0_03-b07 (Sun Microsystems Inc.)

I find this a very strange problem as we did not get any errors during the freeze.I hope there is someone who can help us.
Thanks in advance.
