RabbitMQ crashes recently for no reason

We have a RabbitMQ node running 4GB of RAM on a 20GB disk that is shared with Redis (which does almost nothing), usually handling several hundred messages per second.

However, lately it accidentally started throwing errors without making any other warnings (like Nagios) which is very strange.

Can someone help us debug this issue?

Here's the status:

     {vm_memory_high_watermark,0.39999999961815885},

...done.

      

        
        
        
      

    

Unfortunately, all the information I have to go on is for the lack of error logs at all.

Greetings
