If you've ever retired the Qube! worker off of an older machine and re-used the hostname on a newer machines, you've most likely ended up with 2 worker records in the database with the same hostname, but different MAC addresses. The newer (and running) worker will be in an active state, while the worker entry for the older (retired) worker will forever be in a down state, but not be visible in the WranglerView Worker view.

Since Qube! uses the worker MAC address as the primary identifier, it's possible to have more than 1 worker appear in the list with the same hostname, but they will each have a different MAC address. This can be problematic for actions that take the worker's hostname to specify which worker to perform the action on.

This made it very difficult for the user to actually remove these workers from the database, and the Qube! administrator was forced to run a command-line utility to remove these workers.

These workers are most likely old database records for decommissioned hardware, and should be removed from Qube! at the first opportunity. |
