Ok, I think I understand.
But it would only make a differnce if you have persistant virtual services.
Is this what you are worried about? If so you really just want to
remove the persistance templates from the connection table.
Not all of the connection entries. I am not aware of a way to do that.
Though perhaps the paches sent in response to your post can either do
this or be modified to do it.
Note that if you remove all the connection entries, by any means,
all existing connections will break.
