Problem:
When an NFS server is port-scanned nfsd sometimes exits. This has happened 3 times the last few weeks. Nfsd has been written to exit when accept(2) fails. Unfortunately accept can sometimes make a "normal" return with errno ECONNABORTED and in this case nfsd exits prematurely.
Solution:
Check for ECONNABORTED (and also EINTR, since nfsd uses signals) and continue.
