Long running PII scan results in high CPU usage

Issue/Introduction

What are possible reasons for a long running PII scan job resulting in 100% CPU usage.

Environment

Release : 4.9

Component : Web Portal - PII Audit/Scan

Resolution

High CPU usage by the TDM Portal is symptomatic of either:

1. The allocated memory to be used by the Portal is not large enough to handle proper Portal functionality. When that happens, the Portal will be spending most of its time trying to run the garbage collector and this can result in high CPU usage.

Check that wrapper.conf is configured, and the amount of memory that is reserved for the portal. Using Windows Task Manager (Performance tab) check the amount of system memory available. Increase system memory if needed after monitoring with Task Manager.

2. The TDM Portal has enough memory but there is not enough CPU capacity on the system. Monitor with Task Manager to verify and increase CPU capacity of the machine if needed.
