A problem was reported in RHOSP 17.1.3 environment with TLS-everywhere: nodes periodically fail monitoring without sign of actual problems in rabbitmq logs.

Although this looks close to https://bugzilla.redhat.com/show_bug.cgi?id=2290861 / https://issues.redhat.com/browse/OSPRH-13633 , error pattern is different and tlsv1.2 was set in configuration.

In /var/log/messages I can see the following message indicating that mnesia is not well:

Jun 25 12:44:32 controller02 rabbitmq-cluster(rabbitmq)[110768]: INFO: RabbitMQ server could not get cluster status from mnesia

But I can't find related errors in this node, or other node's rabbitmq logs.

I want to kindly ask for expert look here

Bug impact
RabbitMQ crushes periodically and may break some overcloud operations

Known workaround
None
