Description (partial)

Symptom:
Device may unexpectedly reset due to:

%SYS-6-STACKLOW: Stack for process Flow Exporter Timer Admin running low, 0/6000

As soon as this message is seen the device will reset and return to normal operations.

Conditions:
Device has Flow Monitor configured in such a way that it will monitor its own exports, i.e. the exporter has output-features enabled, or the exporter is sending via a tunnel and the monitor is configured on the physical interface of that tunnel.

The cache also has to be full and entering Emergency Ageing mode (can be checked from "show flow monitor NAME statistics).
