Hi Dimitri
I can't see how bug #55427 could be relevant for this problem.
I am also not able to find in that bug any mention to configuration
parameter to select asynchronous registration.
At any rate, as we already discussed some time ago with you and the other
KIT guys, that error means that after having issue the submission command
(bsub/qsub/...), the lrms jobid was not returned within 200 seconds.
It you want to increase that timeout, this is possible. The relevant
attribute is:
blah_child_poll_timeout
in /opt/glite/etc/blah.config
But 200 seconds (more than 3 minutes) seem a lot to me and I wouldn't
suggest to do that.
when there are such problems in the batch server, probably the right
thing to do is to disable new job submissions using the
glite-ce-disable-submission command (assuming that you are an admin of
that CE).
See: http://grid.pd.infn.it/cream/field.php?n=Main.HowToDrainACREAMCE
for more detals
Please have a look also at this page:
http://grid.pd.infn.it/cream/field.php?n=Main.Self-limitingCREAMBehavior
which explains the details of the machinery that automatically disable new
job submissions when certain conditions are met
Cheers, Massimo
