First question, at what point are entires removed from the
sys.conversation_endpoints system view?
As there is a status of CLOSED, I'm assuming that it doesn't occur when the
converation has been ended by both sides of the dialogue, otherwise when
would an entry go into that status?

The second question (and problem), is that we have a situation in which the
target sys.conversation_endpoints view is just growing in size, and all the
entries are in the CLOSED state (processing is for a single message in a
dialogue, and processed immediately). By the initiators
sys.conversation_endpoints is empty. Is this normal behaviour?
I should also say that in this enviroment we have seperate SQL Servers,
within the same Domain, each running under a different domain account.

Any answers / help greatly appreciated.
