  Log:
  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.
