Environment

16.1

Cause

The EnforceConnector service may require more Java heap assigned to operate correctly.

Resolution

Go to Advanced Settings of your detector, and double the value under UDS.EnforceConnector.MaxMemory to see if it resolves the issue.

Additional Information

See also Should the Java heap sizes for the Detector and EnforceConnector services be the same size.
