Description (partial)

Unexpected device reload when device-tracking feature (SISF) is enabled and left running for a long time.

This problem may happen over time if device-tracking MAC entries are repetitively deleted and created. The time between deletion and re-creation of the same MAC entry needs to be less than the Crimson DB's garbage-collection time to trigger this issue.
