discovery_server temp queue with subject _$HUBALL is backing up

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

A queue with a name like "t_0" subscribed to _$HUBALL on my secondary hub is backing up and the messages are not draining quickly enough.

Environment

DX UIM 23.4.5
discovery_server 23.4.5

Cause

large environment/slow network

Resolution

On a slow network or one with high response times between hubs, this queue can get backed up temporarily.   It is not generally a problem and can be ignored as long as the messages are still draining.

If they have stopped draining, you may need to right-click the queue in the hub GUI and select "Empty" to clear the backlog.

In DX UIM 23.4.6 (CU6) there will be a way to disable the creation of these queues.
