> NetAccept got a client_vc and call new_ProxyMutex() to assign a mutex.
> And the HttpClientSession, HttpSM, HttpServerSession, server_vc also share the same mutex.
> The HttpServerSession and server_vc will put into ServerSessionPool and may assign to next new client_vc.
> The HttpSM::attach_server_session() only set the mutex of HttpServerSession to the mutex of HttpSM after get a HttpServerSession from ServerSessionPool.
> But it forget to set the mutex of server_vc to the mutex of HttpSM.
>  
> {code}
> void
> HttpSM::attach_server_session(HttpServerSession *s)
> {
>   hsm_release_assert(server_session == NULL);
>   hsm_release_assert(server_entry == NULL);
>   hsm_release_assert(s->state == HSS_ACTIVE);
>   server_session = s; 
>   server_session->transact_count++;
>   // Set the mutex so that we have something to update
>   //   stats with
>   server_session->mutex = this->mutex;
> {code}
> But I can not found any issue, Is it by design?
> Or it is hard to locate the problem, due to my limited knowedge on HttpSM.
