Although seek errors are the results of programs performing IO
operations on invalid disk positions, the fact that you are getting the
errors is due to the database corruption.

I would start to suspect that the problem lies with the disk
drive/subsystem!

The only time I have seen database corruptions, in 20+ years (15 with
IB/FB), has been the result of:

- Server Abends (abrupt shutdowns), even with Forced Writes = ON

- Disk drive/controller failure
