Removing old thread from statistics after thread deletion

Scenario: thread deleted from NetConfig. Other threads still show it as part of statistics when looking at the status from NetWork Monitor. I need a sure fire way (step by step) of getting rid of this information.

I know it has something to do with hcimsiutil -R, but don’t know the rest. I tried some commands in the test environment and got it to work only after I had to mark all the threads as dead after all engine processes were down again. Something got screwed up.

A little help would be appreciated.
