Subject decompression overran buffer (179)
Author rogervellacott
On a production database which has been running rock solid for 18
months, I have had data corruption twice in the last two weeks.

The server log says

internal gds software consistency check (decompression
overran buffer (179))

Server is NT4. DB version is IB 5.6. Database size is modest (110
mb). Largest tables about 120k records.

Validation finds no errors unless I check Validate Record Fragments.
It refuses to back up (failing with the same error report) unless I
first remove all indexes and foreign keys.

The data corruption affects one or two records, and on each occasion
they have been in different tables.

Can anyone tell me what the error means, and what is likely to be
causing it?
