setSession to nil in recreateSession action to avoid unnecessary CloseSession #700

Conversation

In the client.go monitor loop, the recreateSession action builds a new session on the assumption that the server is no longer holding the previous. It does not clear the value of the Client's atomicSession, which leads to CloseSession being called in ActivateSession even if there are no old sessions on the server to be removed.

This behavior is referenced in issue #673.

I think this is a good catch and I agree. I hope this fixes the issue in #673

I'm going to cut a new release once this is merged. @law-dwg could you maybe test if this fixes your problem as well?
