Kevin,

For some reason the LDM on atm.geo.nsf.gov exited this morning.  It was down
until about 10 am my time when I rebooted atm.  Data should have
started flowing correctly after the reboot, but it has apparently not.

I logged onto atm and saw that there were a lot of runaway processes
that I had to kill.  The load average was up to 92, so the machine
was basically not getting anything done, including LDM ingest and
relay.  I deleted and remade the LDM queue and then restarted the
LDM, and things seem to be running once again.

I should be around.  I look forward to meeting you.
