when I upgrade my application to JBoss 4.0.3sp1 (from 4.0.2) I've got a big problem with sql connections...
After a few minutes, they are all closed when I try to get one (so I receive a connection timeout when Hibernate try to get one) ...
Is there something change ?
Is there a specific parameter to put in the xml file (the one that configures sql connection) to get correction connections ?
I've got the same problem with mysql and sql server... running on windows or Linux..
so I downgrade to 4.0.2 .... :-(
