Steps to Reproduce
1. Run load test scripst by gradually ramping up user load.
Root Cause
A defect or configuration issue in the operating environment. The resource adapater connection pool implementation for JBOSS (IronJacamar) was not tuned approriately to cater to user / application load.
Resolution
Make the following change to the operating environment:
1. Please modify the “ironjacamar.xml” as below and repackage this into the prpc_j2ee14_jboss61JBM.ear/pradapter.rar/META-INF replacing the existing one.
<?xml version="1.0" encoding="UTF-8"?>

<use-fast-fail>true</use-fast-fail>
</validation>
</connection-definition>
</connection-definitions>
</ironjacamar>
2. Re-deploy the re-packaged prpc_j2ee14_jboss61JBM.ear into your JBoss EAP6.1 server.
3. And Restart server/application.
