APAR status

  • Closed as program error.

Error description

  • During an invocation of a command or series of commands via the
    CLP (Command line process) running in the background under a
    nohup.  If the parent shell exits, at the end of the invocation
    when it returns to the calling shell it can return a DB21018E
    and exit.  This only happens of the parent shell that issued the
    command via nohup subsequently exits.
    

Local fix

  • If possible avoid exiting from the parent shell while using
    nohup
