Environment

  • Policy with diffserv replacement and meter configured
Cause
This is caused by a software defect that can be tracked via CR xos0067079.
Resolution
Upgrade to a fixed software release.  This issue was resolved in 16.2.3.5-patch1-3, 21.1.3.7-patch1-5, and the initial release of 22.3.1.
