The installation was using Firebird 2.5.2 SC. There was near 800000 transactions/day, more than a half between 8:00 AM and 15:00PM.

The system runs fine and the performance was good except the problems of page conversion, some minutes the System was frozen (10 minutes) at 9:30 AM, and the crash i had deleting one attachment.

1. The frozen may be because a sweep was executed. I had sweep interval set to 20000. Now is disabled and executed at night.
2. The page conversion, i think is solved, when we corrected the overhead generated by the transactions.
3. The crash deleting the attachment, is complicated to reproduce now, because I think the source is the amount of transactions. I'm worried with this one, because I don't like engine crash.

May be this amount of transactions is not good for Firebird.
