Hello friends.. I'm having some issues with 2 app servers dishing out the below error for about 20 minutes and then it went back to normal.. I checked for network or server related issues and didn't find anything so I'm left at the DB or app level.

<log realm="mcx-server.server.session/10.116.102.100:58790" at="Mon Feb 22 17:45:31 CST 2016.833">

This is related to the database setup. Hibernate simply delegates the connection request to the JDBC DataSource or Driver.
If there's a connection request failure, then you need to check the external connection pool, JDBC driver, and the database settings.
