Reflector in 5.5.5 got a lot worse

Hi.

I recently tried to upgrade DSS from 5.0.1.1 to 5.5.5 but finds the reflector (relay) part of the server to have gone from partly okay to worse. Here is what I found out.

1) The server don't like to relay more than 14 (double) streams. No problem with that in 5.0.1.1

2) Disabling a stream in relayconfig.xml manually and then execute

    # killall -1 DarwinStreamingServer

    works well, but enabling a stream manually and then

    # killall -1 DarwinStreamingServer

usually doesn't restart the stream. The server needs to be completely shutdown and then restarted.

3) The server sometimes apparently for no reason stop relaying/reflecting streams after a while and hence 2) the serverprogram needs to be completely stopped and started again. Disabling/enabling the reflection of a specific stream doesn't work hence 2)

4) The server sometimes apparently for no reason stop reflecting either the video or the audio and hence 2) the serverprogram needs to be completely stopped and started again.

Regarding 1) when I add an extra stream beyond 14 (double0 streams to be refelcted, the total number of streams being reflected by the server varies between 4-10 (double) streams and I can't seem to find any explanation or warnings in any log files.

Has anybody a similar experience with problems on reflecting/relayin streams ?

Has anybody any suggetions on how to resolve this ? Can the server be told to report errors to a logfile or something similar ?

Here is a sample of the relayconfig.xml.

The part of "udp_ports" is not supported in the web based gui control of DSS.

Kind regards
