>A wild, wild, wild shot here (Craig, you've "forgotten more about tables and buffers than I now know"): is it possible you're running out of disk space either in enroll's directory or (more likely I think) in the SORTFILES= or TMPFILES= directory? Maybe it's dying as it tries to update the CDX?

All this is on a local drive with plenty of free disk space. But, as a thought, I'll try running a scan disk and a defragment. I've seen things like this before cause weird problems.
