Subject FB freeze
Author Zsazsi
Hi everyone!

We have FB 2.5.2 SS running on Win2003/x32 and Win2008/x64 servers. around
50 - 150 user connects to de databases .
Every now and then some of our clients' FB server service freezes at the
time we issue an ALTER DATABASE BEGIN BACKUP or start an nbackup session.
After the freeze the FB service stops responding, and only hard stopping
the process helps.

I couldn't identify any problem at the database or environment level. Some
10057 and 10061 error can be found in the firebird log before the freeze,
but these messages are quite common even the system and the nbackup
sessions otherwise working well. The database sizes are around 10 - 30 GB
and are fully backuped and restored at every weekend.

Any idea what could happen and how can I avoid the phenomenon?

Best Regards
