Error description

  • While trying to activate event monitor writers  when some node
    failure recoveries are being done on other partitions . The node
    failure recovery triggered the panic because we interrupted the
    subagent doing the event monitor activation with a
    SQLE_PDB_INTRPT_NODEFAIL_EVMON_SUBAGENT interrupt. This locally
    generated interrupt does not need to reply to any coordinator
    which is causing the panic.
