    sbin/nfsd            nfsd.c 
  Log:
  MFC src/usr.sbin/sbin/nfsd.c:1.29:
  
    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.
