The problem your seeing is probably a limit in Firebird prior to V2
that restricts the record space for a table to about 70 million KB,
including record headers and back versions - large blobs don't count.
You've got somewhat more than 29 million records so you may have
run into that problem. A backup/restore will fix the problem
temporarily, but the better intermediate solution is to archive some
of the records in another table. V2.0 corrects the problem totally.
