Unexpected Error on Firebird 5.0.1 SuperServer

[dawkow]

We have encountered a rare issue while using Firebird 5.0.1 SuperServer on Windows. Over the past three months, our application has experienced this error three times:

Operating system directive SetFilePointer failed. An attempt was made to move the file pointer before the beginning of the file.

When this occurs, all database operations become unresponsive, and the only solution we have found is to restart the Firebird service.

Occured 3 times over the past 3 months but on different clients.

Could you provide any insights into what might be causing this issue or what we should gather for more information when the problem appears.

Could you check if any file in %ProgramData%\firebird or in the Firebird's temp folders is bigger than 2GB ?

I'm going to close the ticket shortly if there will be no additional info.

I added extended logging of files bigger than 2 GB and waiting for the next error.

Thanks, will wait for next message.
