<p class="MsoNormal"><span style="color:#1F497D">We’ve done a nearly identical migration two months ago for our test IDP and the first of this month for production. We’ve gone from Solaris to everything exactly the same as yours with the exception of Java.
Due to warnings about OpenJDK we instead use java-1.6.0-sun-1.6.0.81-1jpp.1.el6_5.x86_64 which is available in the Redhat repo rhel-x86_64-server-6-thirdparty-oracle-java.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">The production IDPs have been fine. We have had two occurrence with the pair of test IDPs in the eight weeks they’ve been in place that were similar to what you describe. In both cases a Tomcat restart fixed
it and we were never able to determine the cause – nothing logged anywhere, just a non-responsive hang.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Given the similarities of our environments I would be very interested in what you find and willing to share our findings. Unexplained hangs are unnerving.<o:p></o:p></span></p>

<p class="MsoNormal">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?<o:p></o:p></p>
<p class="MsoNormal">Or, does anyone see any potential problems with our setup?<o:p></o:p></p>
