Issue
WebLogic process hosting RSA FIM becomes unresponsive and must be killed to restart.
Core file analysis shows Java deadlock in Java_java_net_Inet6AddressImpl_lookupAllHostAddr
Cause
This is a known issue in Java 1.6 where some DNS lookups of hosts with lots of IP addresses will cause a deadlock. 
Resolution
Upgrade to JRE 1.6 version 31 or later.
A work around is to add the problem hostname to /etc/hosts.
