Hmmm.... If rebooting will solve the problem and you don't have a very long running transaction, then I doubt that garbage accumulation or collection is the source of the problem. Nor is there anything else wrong with your physical database - fragmentation or whatever. I'd look at memory usage - using both Firebird and OS tools. Look for paging before you reboot. After you reboot, track memory usage daily or more often. It doesn't take much of a leak - or unfortunate caching - to built up over month of 27 tps. Accelerating the move to 2.5.4 would also be a good idea, both because it may correct the problem and because it probably offers better diagnostic tools for this sort of problem. Good luck, Ann
