I m under WM 9.7, and as described in WM documentation :
Note: The WmPKI and the WmTNPKI packages which provide functionality for using
PKI profiles has been deprecated as of Integration Server version 9.7. There is no
replacement for these packages.
but IS try to load WmTNPKI, when :
[ISS.0028.0061E] Unable to load system package WmTNPKI due to dependency on non-system packages
Can you please help to understand why IS try to reload this package.?
Sounds like SAG has overseen some dependencies in the new release.
As a workaorund you can remove the following line from the manifest.v3:
7.1
Then it should load.
After that you can try to disable it finally.
But additionally I agree with Tong that SAG should be informed either by Incident and/or Brainstorm FeatureRequest to get this corrected in future releases.
