I have tried cutting the number of files from 1200 to 250 and that does help, however it doesn't seem to be a problem with memory because I monitor memory use while the script runs and there is plenty of memory available.

I would recommend contacting support@harris.com with respect to the vague error message from the export method. Those folks know a lot of tricks for debugging situations like this and can be a bit rabid (in a good way) about getting to the root of a problem.
