@VadimPlh does it look similar to #5276? Do you think #5375 will help here?

I think not
It is another test. We have different services for connection_limit and connection_rate_limit

doesn't look like redpanda bug, rpk consumer just failed to stop in 600 seconds

also happened only once in a long time, so closing as won't fix
