This implicates a bug in TORQUE we think we fixed in 2.0.0p0 (grab the
latest 2.0.0 snapshot from Nov 11).  We were never able to reliably
reproduce it, but I haven't seen it happen since.  The problem was that
a timeout wasn't properly detected and left stale data in a buffer; the
stale data was then incorrectly retrieved on the next stat.

In the lines prior to your error message, is there a long gap in time?
That shows that a jobstat() timed out, followed by a nodestat() that
returned the previous jobstat information.

You'd need to install the 2.0.0 pbs_server and client libs, and rebuild
maui with the new client libs.
