You mention that you sometime see this after a redeploy.  Depending on how
you've redeployed, have you successfully clustered the nodes in the first
place?  The error means that some of the tables in Erlang's Mnesia
distributed database upon which Rabbit relies to maintain broker metadata
weren't found, suggesting that some prior state or configuration perished
during your redeploy process.

Best regards,
