David I've seen this where a GCI/CALLC routine was linked into a UniData kernel and it reused the stderr file handle. The result was the stderr data stream overwrote the file which currently was allocated to that handle (whoch UniData was using for the VOC).
The giveaway was to perform an "od -c" of the VOC - many application error messages overwrote the file header. Hope this helps...not sure off the top of my head whether UniVerse usage of handles is similar - but worth a check.

The first incident was tracked back to the possibility of errors on the SAN. Hardware was replaced and the file has been resized (I assume by this it has also been moved to a different area on the disk or disks) The following incident has no hardware indications in any log thus making it a little hard to trace where the issue occurred. The customer is, understandably, concerned this may happen again as unfortunately both incidents have had a major impact on their business. I am curious to find if any other sites have had a similar issue. Both incidents were backward link errors in the same items. As noted above, the file was resized between incidents and I assume is now in a different area on the SAN. I have found nothing to date in any log on the system. Any suggestions are welcome.
