Collector.Service Constant High CPU

Need some info on where to look for reasons why the collector.service stays constantly at 80/90% cpu.

When we perform monthly Windows patches/updates & reboot; it's good for about 2 to 4 days; then spikes up and stays at 80/90%.

Memory doesn't spike, stays around 7Gb's of the 16 total.

Usage:

NPM v12.2

One (1) Win2K12 Box, 6 Cores, 16Gb's RAM / Separate SQL

NCM = 376 Nodes

SAM = 477 Component Monitors

NPM = 441 Interfaces

IPAM = 6068 IP Addresses

UDT = 12423 Ports

Syslog = None

NetFlow = None

Things we've already done:

If we stop/restart the service, it takes about 5 mins for CPU to get back up to max

Tried this, with no results:  High CPU load in SolarWinds NPM service - SolarWinds Worldwide, LLC. Help and Support

Any help greatly appreciated....
