Hi Ryan,
>My understanding is that gbak does a sweep while doing a backup, which
happens nightly, so sweep should be happening then (if I understand it
correctly that is).
You are wrong. Gbak does not do sweep, it runs snapshot transaction and
reads all records in all tables - and, with some conditions, it can
clear some garbage versions.
Restart should fix oldest active stuck - if it's a real restart (Classic
processes sometimes remain active). Did you check that all processes are
down? Or did you restart hardware?
And it also could be another problem, more complex... I can't say more
without detailed investigation.

This is Classic, so yes, automatic sweep is disabled. My
understanding is that gbak does a sweep while doing a backup, which
happens nightly, so sweep should be happening then (if I understand it
correctly that is). Also, running a manual sweep hangs indefinitely.
As for the active transaction, restarting Firebird doesn't fix the
problem. The ONLY thing that fixes the problem is restoring from a
backup file to create a fresh file. According to Sinatica, there are
no active transactions while the problem is being exhibited. I will
check the raw MON tables, but would restarting the Firebird service
not terminate any active transactions?
Thanks for all the quick responses!
Ryan
