Resolution

IMPORTANT: After following the below workaround, the user will not be able to re-inject the RDQ files back in to the Log Decoder for processing. If this data must be reprocessed, contact RSA Customer Support for assistance before continuing. 


  1. Connect to the Log Collector via SSH as the root user.
  2. Change to the /var/lib/rabbitmq/mnesia/sa@localhost/queues directory.
    [root@LOGDECODER queues]# ll
    total 24

  3. Remove all the files from this directory.
    rm -rf ./*

  4. Stop all of the associated services.
    service puppet stop
    service collectd stop
    service mcollective stop
    stop nwlogcollector

  5. Kill the "beam" and "empd" processes for rabbitmq server.
    ps -ef | grep -i "beam"
    ps -ef | grep -i "empd"

  6. Trigger a puppet catalog run which should start all of the services including rabbitmq-server successfully.
    puppet agent -t
