Subject:   -25- Why does ksh lock up if one's home directory is NFS-
                mounted?
Date: 15 Oct 1995 00:00:01 EST

  ksh(1) uses a single ~/.sh_history file for all of a given user's ksh
  processes, so must be able to lock that file. Locking is robust for
  local files but not over NFS. Install patch 547 (or its successor) to
  fix some known NFS bugs and be sure lockd is 'chkconfig'ed on and
  rpc.lockd and rpc.statd are actually running.  If all else fails, set
  the HISTFILE environment variable to a file on a local disk.
