Unknown event '%1!' requested for process '%2!'.
An unknown event has been passed to srv_event(). This error may also occur during thread creation, which means that Open Server cannot assign an event to the new SRV_PROC.
Pass only these events to srv_event(): SRV_DISCONNECT, SRV_URGDISCONNECT, SRV_STOP, user-defined events.
Symbolic constant: SRV_ENOEVENT
