Thanks Karl,
I have tried steps you suggested and it worked on one instance.
But on another instance i am still not able to resolve this issue. Along
with steps you mentioned, i tried recreating DB instance again, setting up
new MCF instance , cleaning locks and then starting agents first & then
tomcat. But issue still persists.
If i try to run ./start-agents.sh, i get this error for agent A.
ERROR 2014-07-08 13:32:19,823 (Agents thread) - Exception tossed: Service

But if i try to run ./start-agents-2.sh, i see similar error but agent B
