[jboss-user] [JBossMQ] - User: guest is NOT authenticated

We have 14 Jboss 4.2.2 systems running on the same server, at midnight they all simultaneously update their runDate in the database (Oracle) and occasionally (twice a week ?) they produce this error, any idea what might cause this ?? The only thing I can think is some kind of limit to number of sessions connecting to the underlying oracle database. Thanks, Chris Milburn.
