Which Traffic Control components are affected by this PR?

• Traffic Router

What is the best way to verify this PR?

1. If using Dev CIAB, Create Terminal to the TR container and navigate to /opt/traffic_router/temp/ directory. After every restart of TR, there should not be any czf*.json files created prior to the current start up of TR.
2. Same applies to any environment where TR is deployed. No new czf*.json files should be retained under the /opt/traffic_router/temp/ directory after the TR restart.
3. However, as a one time cleanup activity, all previously created temp files under /opt/traffic_router/temp/ directory has to be deleted.

If this is a bugfix, which Traffic Control versions contained the bug?
