ISC ERROR MESSAGE:
file is not a valid database
(get_number_messages_waiting)
Error occured at 03/13/2003 06:18:09 PM ISC ERROR CODE:335544323

I see this in my server log after a few days.
Once this error appears the server has to be rebooted because no one
can connect.
I am using IBO 4 version H on Delphi 6 SP 2 with the runtime update
1.
The server is a NT service app (win2k sp3) that is the middle tier
talking to FB 1.02
After a reboot the server runs fine for a few more days.
Gfix reports no errors in the .gdb file.

When I disconnect after a request comes in I do disconnecttopool so
I can reuse the connections.

Does anyone know anything about this? It is starting to drive me
nuts
