This WU has hung at least four times, CPU utilization drops to zero, then
segfaults

There's no data for this WU in the stat DB

[kasson]

The 66 (102) return codes are the major class of errors that we can't yet handle well with the new client (6.23).

[parkut]

Stopped process, renamed work dir, and queue.dat, and restarted client.

was assigned the same work unit. Hung again at 30% complete

Found the same situation again this morning, and was again assigned the same work unit.

I suspect it will again

[toTOW]

If I can remember well, the SMP server usually resend the same WU three times before assuming it's lost and moving to another. But sometimes, it doesn't work and some people get the same WU indefinitely.

If it happens with the WU someone from the PandeGroupe will have to remove it manually.

[parkut]

ran a different unit, then got 2665 (Run 2, Clone 717, Gen 58) again. hung at 30% again.
restarted. got same wu assigned. stopped client immediately, deleted WU. restarted.
was assigned a different unit.

[parkut]

Found same situation again this morning. Machine was again assigned
2665 (Run 2, Clone 717, Gen 58), again hung at 30%. deleted and restarted
got the same WU two more times before getting a different WU.

How do we get PandeGroup to delete it permanently?

[kasson]

done.
