Log:
Bump up the NFS server dupreq cache limit to 2K (from 64). With a small
duplicate request cache, under heavy load a lot of non-idempotent
requests
were getting served again, resulting in errors.
How does increasing the cache size fix this problem?
Fundamentally it doesn't, this change just pushes it out of the regime
where it's trivial to overflow.
Why is it hard to do a real fix? Or is this a temporary bandaid?
