Hello,
we've started to have a problem with the qmaster process on one of my
SGE cells.
Basically, it starts to eat up large amounts of memory (and then dies).
Seemed to happen more or less out of the blue (i.e. running fine for a
while, suddenly stops - in fact, it ran fine for a couple of months, and
we had this happen for the first time about a month ago). However, a
couple of tests I ran today seem to indicate that it's the number of
jobs being submitted that triggers it (as in, we managed to trigger it
simply by submitting a lot of jobs in a short space of time).
Unfortunately, a lot of jobs being submitted in a short space of time is
our standard use case :)
This is on SGE8.1.3.
I did make me think of the old 'schedd_job_info can cause immense memory
consumption' - as I do currently collect job info - but I thought that
that was fixed? Should that be fixed in SGE8.1.3?
