IDL process stalls [message #73792]

Hi everyone,

I have a problem with a very resource-intense IDL program. It uses
several Gigs of RAM (sometimes including swap memory) and runs at
around 100% CPU for a long time (ie. days). In most cases the program
runs just fine without problems, however sometimes it stalls. There
has been no exception or error thrown, it just 'hangs' in the middle
of the main loop of the program. The only thing that happens is that
the program seems still running but nothing happens anymore.
Incidentally the CPU and memory load goes down which indicates that it
somehow "lost contact". But, as mentioned, IDL itself doesn't stop or
note that anything went wrong. I wonder if it is related to other
memory-loaded tasks running on the same machine on a different CPU.

My questions: Did anyone have the same problem already? Any idea how
to trace the problem? I should mention that the code runs on IDL 7.0
on ubuntu, 8GB RAM, intel Quadcore.

Thanks for your suggestions.

T.
