Hi,
For superserver this should be as high as possible. Why you
recommended 1 value? I always set it to highest possible value in
current environment compared to size of database. And i
is too high for Firebird SuperServer, it should be set to 1.
You can use optimized Firebird configuration files

Nevertheless, I'll try on a physical machine as you and Carlos suggest
and see how
nbackup to lock database before VM snapshot, in this case
only delta will be at risk.
However, nbackup-only solution is not smart, since it does check an
integrity of database, as gbak does.
We recommend to use combination of nbackup and gbak.

Hi,
Probably you mean Lock conflict, not a true deadlock (full error text
will help).
If you see transaction number in the message, you can track it using
MON$ tables, and then find out which connection has started it.

You can use IBDataPump free tool. It allows data pumping between exact

Hello,
I'm facing a problem where the firebird server v2.5.4 on win 2012
server in superserver mode is leaking memory. Currently I'm at ~5GB usage.
Don't have any
for it.
If problems continue, you can export data using our proprietary
IBBackupSurgeon tool (http://ib-aid.com/en/ibbackupsurgeon/), which can
export data on low-level.
