mod_limits: Only count connections with associated sessions I suspect some (all??) network backends and some edge cases cause ondisconnect to be called more than once. mod_c2s and mod_s2s already handle this, skipping cleanup if there is no session associated. Sessions are assigned very early on in onconnect, so it seems like a reliable way of counting.
