Error description

  • When offline routing rules have been configured within QRadar
    (Admin -> System Configuration -> Routing Rules), large
    amounts of reverse DNS lookups can be generated.
    This can cause issues in some customer environments with their
    DNS server load.
    The issue described only occurs when forwarding
    "normalized' data, not raw payloads.
