It's even impossible to stop the FB Server via control panel applet - we have to do it through Services. There are no errors in firebird.log when this happens.

Try configuring GCPolicy in firebird.conf to 'background'. Remember to get the users offline and stop/restart the server to get the new setting into effect.
