6.4.0.4

Description (partial)

Symptom:
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.

Conditions:
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.
