Problem with tomcat hanging on Shib 2.4

[John Kamminga]

We've migrated our production Shibboleth environment from Solaris 10 to Redhat 6 and are now experiencing problems with the app becoming unresponsive every couple weeks. A tomcat reboot fixes it, but we'd like to find out what is causing it. Has anyone else experienced issue migrating to or running on Redhat 6?
Or, does anyone see any potential problems with our setup?

Here is our environment setup on a Redhat VM.
Redhat Linux version: 2.6.32-431.20.3.el6.x86_64

Shibboleth Idp 2.4

Tomcat  6.0.24
JAVA_OPTS=" -Xmx1024M -XX:MaxPermSize=512M -server -Djava.library.path=/usr/lib64 -Djavax.net.ssl.trustStore=/jdk/cacerts"

Java -version:
java version "1.7.0_55"
OpenJDK Runtime Environment (rhel-2.4.7.1.el6_5-x86_64 u55-b13)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)
