> Connection to mxosrvr often hangs.  From the master-status page, it shows that it's in the 'CONNECTING' state, but never got through.  pstack on that process shows that one of its thread is waiting for pthread mutex lock and sits there forever.  On sqtopl7, this problem is currently preventing any connection being made.
