hi all,
back in 1998 and 1999, a few folks described a problem with long IDL
jobs on solaris going to sleep (0% CPU usage) mid-way through. Henry
Throop provided a fix involving switching from the GENVER license
manager to FLEX.
i'm encountering the same problem now w/ a node-locked license running
FLEX, for both IDL 5.3 and 5.2.1 (this is a multi-processor machine).
the test code Henry used:
pro hang_bug
for i = 0LL, 90000000LL do begin
a = dist(50)+randomu(seed,50,50)
a = a^2 + a
if (i mod 1000 eq 0) then print, i
end
end
causes IDL to fall asleep around 1-3 hours in. our sys admin folks say
this shouldn't be a license manager problem, since it's node-locked, and
thus only checks the license at the beginning of the job.
i've also encountered similar problems w/ a server license running IDL 5.4.
it also is a solaris machine, but only has a single processor.
has anyone else figured out another fix? any help would be much appreciated.
thanks!
best,
-Johnny
