More on this: My logs are full of messages about faulty gfid. My patch
makes them non fatal, but I suspect they can still be harmful in some

While it seems to work, I very rarely have odd failures that I cannot

to investigate? How can gfid mismatch so often? 

I also have a huge amount of this, which seems to be have no real
consequence. Opinion?
