Failing to reconnect to an NX session with the error: "error in locking authority file"

Question

I am able to start an NX session without any issues. But, when I 'disconnect' (leaving a persistent connection, as opposed to 'terminate'), I am unable to reconnect. Here is the error from /var/log/messages:

    Aug  5 19:05:41 praveen NXNODE-3.5.0-3[20703]: ERROR: NX> 596 ERROR: NXNODE Ver. 3.5.0-3  (Error id e77ECD3) [e77ECD3] Logger::log nxnode 2963

I am on a RHEL6.1 x86_64 machine.

I tried running xauth -b quit prior to reconnecting to the NX session. No luck with that either.

Does anyone know how I could get rid of this error? I find NX to be much snappier than VNC and would love to get this to work :) Thanks in advance!

The problem seems to happen when you have duplicate entries in your /etc/hosts. Here is the xauth bug: http://www.kerneltrap.com/mailarchive/openbsd-bugs/2009/3/8/5118304

Fixed the problem by removing the duplicate entries in /etc/hosts.
