Ouch. That's bad :(

Strange thing is that I am not seeing this at all with CentOS 6.6, which
should behave exactly the same as RHEL 6.6.

Please attach gdb to your client process and try to get a backtrace when

It may also be helpful to include the last few lines of the client
output when run with "-d all".

Then there's also the usual suspects: try turning off opengl, clipboard,
etc.
