public uint ResendTimeout ;


Defines the maximum wait time in milliseconds before the "not acknowledged" message is re-sent. Default value = 1200.

It does not make a lot of sense to wait for acknowledgement forever. This parameter sets an upper time limit at which point reliable messages are re-sent.
