Description From Jose Luis Vazquez 2006-07-03 10:04:18

Dear all,

It happens that GridWay mixes arriving job states if monitoring a big amount of
jobs. A "handmade" solution is to raise the POLL_INTERVAL value in gwd.conf,
but making GridWay wait for a job state before polling again would be very nice
:-).

------- Comment #1 From Ruben S. Montero 2006-09-19 06:26:14 -------

This bug is tightly related with the GRAM version used in EGEE. There are two
possible solutions:
 1.- Not polling a job until the callback of the previous polling action is
received. In general, we do not want this since a callback could be lost, and
so blocking further polling on the job.
 2.- Time out polls, which in turn is equivalent to increment the poll
time-out.

I could not reproduce the behavior described neither with GRAM-WS nor with
pre-WS GRAM from GT4.0.X. I have been also trying to reproduced it with the
EGEE testbed without success. I change the resolution to "WORKS FOR ME", we can
reopen the bug later if the situation arises again and we have more info.
