Description

Issue Summary

Opening /projects/<project-key>/queues will send Cache replication requests of each queue separately. This happens on every load of the page and unique per user.

Environment

Data Center

Steps to Reproduce

Create a SAMPLE Service Desk project
Enable TRACE on com.atlassian.jira.cluster.distribution.localq
Load the Service Desk Queue

Expected Results

A single PUT localQ action is being made per user.

Actual Results

Multiple PUT localQ actions were made. Total amount of PUT trace is equivalent to the number of Queue available in the project

Notes

Reloading of the page will refresh the cache and replicate
Switching between queue in the same page will refresh the cache and replicate
Enabling cache-count mechanism from ~~JSDSERVER-4897~~ reduces the cache refresh to be every 2 minutes on cache expiry

Workaround

To reduce or stop the cache replication made by the Service Desk queue, follow the steps in ~~JSDSERVER-4897~~
