CPU is 100% utilized after upgrading to NCM 7.6

Updated July 25, 2017 

Overview

The CPU for the main or additional polling servers for NPM reaches 100% capacity and the servers are locked. The SWJobEngineWorker2.exe process is found to be utilizing 100% of the capacity after midnight and occurred after upgrading to Orion Platform 2017.1.3 SP3, NPM12.1, NCM 7.6, and NTA 4.2.2.

Environment

  • NPM 12.1
  • NCM 7.6
  • NTA 4.2.2
  • Orion Platform 2017.1.3 SP3
  • All hotfixes installed

Cause 

There are dozens of NCM nightly downloads.

Resolution

Reduce the number of NCM jobs. For example, reduce the jobs to one per vendor, and a few large jobs (one job for Cisco and one for everything else). NCM 7.6 has increased simultaneous downloads from 8 to 25. Go to the Config Transfer settings under NCM Settings to verify that Simultaneous Downloads/Uploads setting.
