rabbitmqctl list_users hangs

[Adolf Misquith]

Witnessing an issue where "rabbitmqctl list_users" command hangs indefinitely. Issue is intermittent. How can I go about troubleshooting this problem?

The version of rabbitmq employed is 3.7.7

Regards,

I had this issue when rabbitmq has too many queues in the broker.

The resolving way is to consume out the queues as fast as possible.

You may check your system resources, GPU, memory, disk etc, make sure the borker has enough resource for serving.

regards.

Thanks, Wesley. 

I have around 7-8 queues configured. Is that too many? 

Assuming this would be problem, how can I go about consuming messages from the queue at a faster rate?

System health looks good, nothing much going on there.

Hello,

That depends on how many message items in the queues.
For me when there are about tens of millions messages the broker seems slow.

You can have multi consumers to consume the content. please refer:

That looks good.

Wesley,

rabbitmq is employed via a docker container. Soon after the container is created, I go about checking with the above command i.e. rabbitmqctl list_users. The volume of messages you are referring to is nearly absent in my case.

OK I see.
Since you are using an odd version of rabbitmq (3.7.7), I suggest you
upgrade to the latest version 3.7.18.

And, docker's IO/mem is generally limited, please make sure it has
enough resource for running the broker.

regards.
