They aren't Firebird error codes but they do have some internal
meaning to Windows. 4294967295 is the maximum number for an unsigned
integer in C. I seem to recall someone once suggesting that it
tended to show up as the result of runaway recursions.

Just a thought though - how large is your firebird.log? Is the log
sitting on a FAT32 partition? Or, worse, is the database on a FAT32 partition?

Control services error 1061 occurs when the service is sent a message
and is not in a state to receive messages.

Hmm, a human could be doing this. Have you someone there with
Administrator privileges, who is running experimental queries at
lunch-time, and tries to cure his problems by shutting down the server?

Or is someone, or a batch job, running a filesystem backup while
users have gone to lunch, leaving themselves logged in?
