Hi everyone,

I am facing a strange problem, connections between websphere ( ND 7.0.0.19 ) and MQ Series (7.0.1) are not getting closed and this will cause the MQ connections to grow until the total connections limit is reached .I get following error in WAS ffdc log :


FFDC Exception:javax.jms.JMSException SourceId:com.ibm.ejs.jms.JMSQueueBrowserHandle.getEnumeration ProbeId:246 Reporter:com.ibm.ejs.jms.JMSQueueBrowserHandle@69f1b559

Any advise on what could be causing this would be greatly appreciated

Thanks,

The application didn't close the connection when it was finished with it, or was making new connections when it already had one open ???

Hi ,

The application was making new connections when it already had one open .

I found also this exception in ffdc log :

FFDC Exception:javax.naming.ServiceUnavailableException SourceId:com.ibm.ws.naming.util.WsnInitCtxFactory.getRootJndiContext ProbeId:912 Reporter:java.lang.Class@389c4b4d

Make sure that any bootstrap address information in the URL is correct and that the target name server is running. A bootstrap address with no port specification defaults to port 2809. Possible causes other than an incorrect bootstrap address or unavailable name server include the network environment and workstation network configuration.
