Apparently, it was the stale connection objects which caused the issue. <code> <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name> <background-validation-millis>100</background-validation-millis> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name> </code> Hope this helps some one who has the same issue and wants to know what could fix it. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/640399#640399] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
