When setting `<shoutcast-mount>` within `<listen-socket>` two sockets will be created: * A normal one with the shoutcast mount set * A second one at (`port` + 1) with shoutcast mount set as ICY source port (`<shoutcast-compat>` set). However you can set `<shoutcast-compat>` manually. In this case also two ports are opened at `port` and `port` + 1 with both being identical in configuration. The code uses the following condition to check if the extra socket must be created: ```c if (listener->shoutcast_mount) { ``` However I think it should be: ```c if (listener->shoutcast_mount && !listener->shoutcast_compat) { ``` This will prevent the listen socket on `port` + 1 to be created.
