Subject Re: Multiple sockets connection TIME_WAIT
Date Tue, 24 Aug 2010 13:42:38 GMT
You need to look into the cache level, think the spring default is to
cache nothing if there is a transaction manager present as there is in
your case.

You may want to try cache_connection at a minimum.

There are OS TCP level config options to configure the TIME_WAIT
window but it may be better to tackle the excessive connection
creation a the jms application level.
