Subject Re: [firebird-support] Firebird 3.0.1 freezes on one table for some 10-20 minutes during backup after gfix/mend
No, we don't use -g.

We are doing immedate restore anyway after each backup. The freeze during backup time greatly increases time when the system is down and unavailable and it is becoming unacceptable.

I have experience that such freeze happened once to the database that soon got corrupted. But it was in Firebird 1.5. Firebird 2 and 3 are very reliable in terms of preventing corruptions and besides there are no error messages in Firebird.log. But freez still happens and it occurs every backup time (when gfix/mend have been performed before).
