Error description

  • Possible trap (FODC) may occur in 'hdrEduAcceptEvent()' due to
    an invalid sequence of connections,
    that is for example trying to enable HADR on a database where
    both hosts are 'standby' due to some
    previous error.
    
    The stack trace in the FODC will look like this (this might vary
    based on the platform):
