When I lose a source stream, the listening clients don't appear to be transferred successfully to the fallback
(2.4.0-kh4 0-gf4141fa)

Code:

It looks like it tries to transfer them but then they disappear?

configuration:

Code:

<relay>
<server>127.0.0.1</server>
<port>8000</port>
<mount>/blank</mount>
<local-mount>/stream1fb</local-mount>
<relay-shoutcast-metadata>0</relay-shoutcast-metadata>
<on-demand>1</on-demand>
</relay>

<relay>
<server>main-server</server>
<port>8000</port>
<mount>/stream1</mount>
<local-mount>/stream1</local-mount>
<on-demand>1</on-demand>
</relay>

<mount>
<mount-name>/stream1</mount-name>
<password>xxx</password>
<authentication type="url">
<option name="listener_add" value="http://localhost:81/listener_add.php"/>
<option name="listener_remove" value="http://localhost:81/listener_remove.php"/>
<option name="auth_header" value="icecast-auth-user: 1"/>
<option name="timelimit_header" value="icecast-auth-timelimit:"/>
<option name="presume_innocent" value="yes"/>
</authentication>

<fallback-mount>/stream1fb</fallback-mount>
<fallback-override>1</fallback-override>
<burst-size>300000</burst-size>
<bitrate>128</bitrate>
<charset>UTF-8</charset>
<mp3-metadata-interval>4096</mp3-metadata-interval>
</mount>

<mount>
<mount-name>/stream1fb</mount-name>
<hidden>0</hidden>
<burst-size>100000</burst-size>
<bitrate>128</bitrate>
<charset>UTF-8</charset>
</mount>

/blank is fed from ezstream locally on the server.
any help appreciated.

this appears to be due to the

Code:

if (client->connection.error)

in source/send_listener

I can force connection.error to 0 before this check & the transfer happens as expected.
It's definitely not a good code change though (completely breaks other things) but I'm a little stuck getting much further than this.
