Error description

  • Combining the --allrepl (-A) and the --background (-B) options
    of 'cdr sync replicateset' or 'cdr check replicateset' will
    crash the connect server soon after in ERCommand thread:

    This crash will repeat as soon as the server restarted and ER
    came up.
    

Local fix

  •  - bring up the server using oninit -D, so without starting ER
     - locate and delete any rows in syscdr:replcheck_restart_tab
    reflecting those two options
       (or update their replcheck_restart_object to contain empty
    string ("") rather than NULL)
     - cdr start
