JC, are you implying the server is misconfigured and ssllabs would tell me why?  Regardless, it's on the intranet and not publicly accessible not that it is a server in my realm of control anyway.   We too just upgraded to RedHat 6.5 and I was thinking I could roll-back the SSL libraries to a previous release although that is less than appealing.

This came up for us with the move the RHEL/CentOS 6.5, which rebased the
openssl version to 1.0.1e. Given that xymonnet is using openssl to handle
this, I'm not sure how easy it would be to do much more... Our solution
was to fix forward.

If your site's publicly accessible, https://www.ssllabs.com/ssltest/ is a
nice site for checking against SSL mis-configs like this. Even this will
call out openssl-1.0.1e compatibility.
