Re: [sr-dev] Dialog module: "CRITICAL bogus event 6 in state 2

It is a race between the 200ok being sent out and the update of the dialog state machine. The ACK is received while the dialog state machine was not updates for the previously sent 200ok. IIRC, in opensips this was fixed by introducing a new tm callback in order to update the dialog state machine as soon as the 200ok was sent out. For now, the only way to avoid this issue is to run with one single listener. This will keep the ACK into the received queue until the listener finishes the processing of received 200ok.
