CPU Over Capacity Alarms are happening regularly in Spectrum.
Dump file stacks are showing adjacency updates happening frequently.


Customer has Overcapacity alarms turned on.
The stacks were showing adjacency updates happening.
Made adjustments to settings already in place.

We can lower max_update_adjacencies_per_batch from 3 to 2.
And increase update_adjacency_thread_priority from 60 to 70.

Add these settings to the .vnmrc file.

When you turn on the over capacity alarms all it takes is a CPU spike to trigger them.
A CPU spike isn't overly a bad thing, either. But the alarm will trigger anyways.
