Description (partial)

A false positive microengine fault can be registered by a device or a stack member under certain circumstances. As a result, the health process triggers a recovery that is unnecessary. Also, to verify that that said fault is indeed a false positive, the following is observed: once such a fault is registered, a troubleshoot is created and the health check within the troubleshoot reports that all NFEs are fully operational, i.e. there are no microengine faults on any of the NFEs.

The likely cause of a false positive is that a microengine was delayed performing a task(s) or waiting for an event), and this is mistakenly reported as the microengine having stopped.
