Symptom
RabbitMQ process doesn't start on the FMC. This leads to a 'system processes are starting' message in the FMC UI.
Conditions
PM status shows RabbitMQ fails to start while its predecessors start properly. The rabbit@localhost.log file will indicate errors 'not_a_dets_file' message when the /var/lib/rabbitmq/mnesia/rabbit@localhost/recovery.dets file is corrupt
Workaround
Delete the /var/lib/rabbitmq/mnesia/rabbit@localhost/recovery.dets file & restart RabbitMQ from pmtool
Further Problem Description
In some circumstances the directory stucture in the work around might be wrong. Check:
var-log/rabbitmq/log/crash.log
Looking for:
exception exit: {{badmatch,{error,{{{badmatch,{error,{not_a_dets_file,"/var/lib/rabbitmq/mnesia/rabbit@localhost/msg_stores/vhosts/45Y9RF6ZKMNMGGWS6HE9BFJT2/recovery.dets"}}},
In this situation the recovery.dets was in /var/lib/rabbitmq/mnesia/rabbit@localhost/msg_stores/vhosts/45Y9RF6ZKMNMGGWS6HE9BFJT2/recovery.dets
