```auto
  else if [fields][log_type] == "paloalto_smtp" {
    csv{
      source => "data"
      columns => ["FUTURE_USE","Receive Time","Serial Number","Type","Threat/Content Type", "FUTURE_USE","Generated Time","src_ip","dst_ip","NAT Source IP", "NAT Destination IP$
    }
    if "

The log message you quoted is just the final "something went bad, shutting down" message. The interesting log message comes before that. Seeing the complete configuration would also be helpful.
