Both of the errors you've listed indicate there's some form of disk problem. Maybe contact the SAN vendor (assuming it's a SAN) and get them to check it out.

the error Could not open FCB for invalid file ID %d in database '%.*ls'. is know to cause data corruption, thread errors and runtime errors

are there different service pack versions on the shipper and shipee?

But SQL needs to be stopped when running that. The aim is to validate the IO subsystem, nor slaughter it.

by the way -

FCB stands for File Control Block, the physical file structure used
by SQL to write in and read data from the storage.

i've had these before when i defragged a database and the log shipping made the same changes on the target.

Almost.

FCB means "File Control Bank"
It's an in-memory structure that keeps track of various pieces of file information for the files in the database.

Defragged as-in a disk defrag tool? Most 'online' disk defrag tools don't support SQL Server and will cause all sorts of damage if they're run on an open, in-use SQL database.

How can you do an index defrag of a log shipping secondary? It's read-only at best. Or do you mean index rebuild on the primary and log shipping copied that over? If the latter caused that error on the secondary, there's something wrong with that DB or server.

are you having a senior moment ? :-P

i defragged the indexes on the primary (or shipper) and when the log is copied across the same changes are applied to the secondary (or shipee)

On one of the three server pairs in question, yes the hotfixes don't match (2282+2187, and I am awaiting clearance to patch)...and of the four times we have had this problem, the mismatched shippee was the host TWICE.
