IDL hangs on futex_wait_private [message #80240]

Dear fellow IDL'ers,

I have a rather nasty problem going on. Recently I programmed a
analysis program and in most cases it runs quite smootly. Once in a
while however, it just stalls, in the middle of a loop. No reading or
writing is done, just plain math. I keep memory requirements low, and
also the specific datafile I'm analyzing does not seem to matter. No
crash, no error messages (also not in system log files). Looking at
the process state it is in: futex_wait_private. Running on linux,
Fedora 14, 32 bit. Has anyone perhaps ran in similar problems? My
feeling is that it might be a thread related thing when IDL does some
parallelization. Any clues? Is there a way to tell IDL to do no
parallelization?

Thanks for your thoughts!

Mark
