Sounds like a resource is being exhausted during the run.
- Check to see if you are running out of memory (including swap) while the code is being run.
- Check if you are filling up a partition (e.g. /tmp if you are on UNIX), or wherever your TEMP environment variable is on Windows.
Beyond that, do you know if: * This happens only on this machine (have you tried others?) * Are there any interesting entries in the machine's event/system logs around this time?
If that doesn't bear any fruit, you could try posting the code here or putting in a call to support.
