Yes -- I have been running under SP/4 even and had 3-4 of those failures in the last 2 weeks or so (since 1.5n). It ran fine with a 2M machine ever since it was installed; it is now 4M and has failed once in similar circumstances, receiving many files back-to-back (after link re-established). I had at first suspected the database stuff might be fragmenting storage, but it could be something within the reader processing, or people are just plain sending bigger files :-) Just thought I would add my $.02 worth in case this was happening elsewhere as well and other postmasters figure a month with out a DMSFREE crash would require a miracle.
