      We had MDS hanging this morning, to a point where signing on server was denied. We had to power cycling the server in order to regain access to it.

      I am uploading "/var/log/messages" and 2 kernel trace dumping.
      I would need you help in interpreting from these logs and let me know
      where is likely the problem, the Lustre, networking, client overloading, and etc.

      thanks
