Rabbitmq start fails

Question

My RabbitMQ server went down and it is impossible to restart it. I tried to restart, reinstall it... I still don't understand the error. This is what I get

BOOT FAILED

Can anyone help with this?

Thanks a lot

I already did. The logs are from the command sudo rabbitmq-server start — tarkovski, Sep 02 '14 at 08:48
maybe the problem is mnesia DB, if you can erase your data, try to delete the mnesia DB here /var/lib/rabbitmq/. note : this WILL DELETE all your data stored to the queue. — Gabriele Santomaggio, Sep 02 '14 at 08:57
Yes, I did move mnesia and it seems to work now. What was the error? Since I didn't do anything in particular and it has been running fine for the last weeks ... — tarkovski, Sep 02 '14 at 09:07
Good question, I don't know exactly, could be an disk error for example. The data-base seems corrupted. — Gabriele Santomaggio, Sep 02 '14 at 09:12
Thanks for your help! My whole system seems to be broken though ... This is really obscure, if anybody has an idea, I would appreciate very much an explanation. — tarkovski, Sep 02 '14 at 09:19

For anyone else looking for this error rabbit,failure_during_boot,

{badmatch,  
     {error,  
      {{{function_clause,  
         [{rabbit_queue_index,journal_minus_segment1, ...

I just dealt with the same issue and what helped was going to the mnesia directories and deleting the queues and msg_store_transient directories.

From what I understand, what happens is that you end up with a bad queue db (for whatever reason -i.e. a sudden power failure, some other process touches the files) which rabbitmq can't parse and so it crashes. Once you clear the queue of messages, it works fine.

Thanks. I was worried about doing that, but it recovered nicely. My affected instance is part of a cluster and it synced up with the other one nicely after deleting the queues and msg_store_persistent (in my case) directories. – David Welborn Feb 04 '19 at 18:59
Thanks, Man. You saved my day – fahad Apr 23 '21 at 17:29
Thanks, after deleting the files, the issue got resolved. And for more info, files will be located under /var/lib/rabbitmq/mnesia/rabbit@/. Here mainly you need to clear the content from these directories msg_store_persistent, msg_store_transient, and queues. – Arjun Thakur Nov 14 '22 at 08:00

I ran into the same issue and this is what helped me.

The Mnesia files in questions were located in /var/lib/rabbitmq/.

I had to delete everything in ...\AppData\Roaming\RabbitMQ\db, not just the Mnesia files (on Windows, obviously).
