we have a websphere application which has 8 jvms and as per WAS administrator the maxconnection is set to 10 which mean the total number of connections to mq queue manager should not exceed 80 from that box at any time but at peak hours we see as high as 600 client channels spawning . does anyone know what could be wrong ? the websphere application connect to mq queue manager using SVRCONN channels on aremote queue mnager. the websphere version is 6 and mq is 5.3 csd07. the developers saying they are properly releasing the connections. is there any other config parameter on websphere side which administrator migght not have configured properly ?

The max number of connection is set for each QCF.
The property is Maximum Connections , and one of Connection Pool properties for the QCF.

Using WAS console to navigate to a QCF Connection pool properties , here is the path
The path for JMS queue connection factories is: Resources > JMS > JMS Providers > Default Messaging > JMS Queue Connection Factory > JMS_queue_connection_factory > Connection Pool Properties.

Cheers
