I believe I finally have an answer for our problem.  We had a corrupted
filesystem.  The filesystem was repaired a week ago.  I haven't had any
problems since.

It seems that the Linux OS gets very confused in its bookkeeping when a
filesystem fills up.  We've seen this many times, and the end results is
always lots of corrupted files.
