Streaming server Connected but no KB sent

[hdradio]

Sending data to my local icecast server stops while server is connected.
Look at the following screens:

and

When I stop the server and start it again from the pop up menu it connects again but it does not send any kb.
If I open the Edit Settings for this server to open it's settings and click OK (without any change), it connects and starts sending data.

Note:
When I run pf all streams are connected to server. Later one stream stops.

Do I understand you correctly, that 2 out of 3 streamings do work fine on your machine but just one causes problems?

When no data is send but you are connected that indicates that the there is either a network issue or a the mixer source doesn't process any data.
In that case (no data send to the server) the server typically drops the connection after some time, e.g. 30 sec.

Have you enabled the NONSTOP option for the related mixer channel?
What other differences are there between the problematic stream and the other two running fine.

The first screenshot is taken some days ago when I had configured two streams.
When this problem happened I took that screenshot to report to you some time later.
The second screenshot is taken yesterday when I had 3 streams configured.

I have ONE LOCAL Icecast server that ALL those streams send their data to.
As you see there is not a network issue because the other streams send their data without problem.
Also all those streams have the SAME mixer source.

I have a dedicated virtual mixer channel (I name it STRM) as a streaming source.
A copy of OUT is send to this STRM channel.
I have enabled the NONSTOP option on OUT channel.

All those streams have exactly the same settings, except the codec used.

As I told you, if open the stream settings and click ok, it starts sending data normally.
(but not from Stop and Start server from the popup menu).

Then please post you exact encoding settings for the trouble some stream.
If really ALL three servers are exactly the same for all other settings...but only the one is causing trouble it must be somewhere in the encoder settings...

The dedicated STRM is not configured as Nonstop?

The first time the trouble stream was the mp3.
The second time it was the aac+.

As I told you the dedicated STRM mixer channel is Virtual and as virtual it does not have a nonstop option.

Here are the config for each stream:

But what are your encoder (profile) setting?
Incl. target sample rate and stereo/mono option..

I was making various tests here but I had no luck in reproducing your issue.
I have configured it exactly like your example.
I just needed to change to ICEcast default config to allow 3 sources (as the default is only 2!) - so I hope you did the same.
What ICEcast version are you using. If not the latest, also try the latest ICEcast (2.4 beta 5 aka 2.3.99.5) may be it is an ICEcast version issue?!
Here are my screenshots...

Yes I have changed number of icecast sources.
I am running icecast 2.3.2 on a raspberry pi for my tests.
I 'll try to update to 2.3.99.3 to check things out.

I assume, it really must be an issue with your Raspberry PI, as I tested several other ICEcast servers without finding any issues.
