Hi,

Problem report form follows...

With OpenDDS-3.5.0, it was possible to use 'use_multicast' option set to 1 in a way that a crashed publisher/subscriber was able to reconnect with other publishers/subscribers when restarted.

It seems that something has changed in OpenDDS-3.5.1 with 'use_multicast' option (please, see report form).

What can I do to have the same behaviour of 3.5.0 of 'use_multicast=1' option ?

Thanks

Hubert

    SYNOPSIS:

        'use_multicast=1' produces a different behaviour from version 3.5.0
        to version 3.5.1 on my application.

    DESCRIPTION:

        Here is my rtps.ini file:

            [common]
            DCPSGlobalTransportConfig=$file
            DCPSDebugLevel=0

            [domain/11]
            DiscoveryConfig=fast_rtps

            [rtps_discovery/fast_rtps]
            SedpMulticast=1
            ResendPeriod=2

            [transport/the_rtps_transport]
            transport_type=rtps_udp
            use_multicast=1

        My application (multiple subscribers/publishers) has run well with
        OpenDDS-3.5.0. Now, with OpenDDS-3.5.1, my subscribers receive a bunch
        of topics every four seconds instead of receving each topic one at a
        time.

        When I set 'use_multicast' to 0, my application runs well.
        However, when a subscriber/publisher crashes and when 'use_multicast=0',
        reconnection is not done when restarting the crashed
        publisher/subscriber, what was possible with 'use_multicast=1'
        (OpenDDS-3.5.0).
