     120processing effectively stopped around 6am this morning, though the
     121full analysis was not complete:
     122
     123 * there are a number of chipRuns that have not finished: 37 exposures
     124are still pending.  This is basically because of point 2:
     125
     126 * ipp014 is unhappy: it is not so unhappy that it has been kicked out
     127of nebulous, but files on it are giving I/O errors.  The failing chips
     128are being caused by this, but coupled to a lingering nebulous error:
     129the rules are forcing nebulous to return the ipp014 instance rather
     130than randomize among the instances.  i'm going to reboot ipp014 and
     131kick it out of nebulous for now.
     132
     133I'm attaching a snapshot of the ganglia load for the past 24 hours.
     134you can see where the test started a bit before noon yesterday with
     135the initial set of machines, and then the point where I crashed
     136pantasks and restarted with and additional set of wave 2, 3, and C
     137machines.  you can also see the problem machines caused by the
     138nebulous distribution (ipp039 and a couple of the ipp04X machines),
     139and the ones that have been giving occasional nfs issues (eg ipp016).
     140I'm not certain if the latter issues are being cause by glitches in
     141those raids, something equivalent to the causes of the ipp005 crashes,
     142or because of poor data distribution.  this is something we need to
     143investigate.
