*Here is the situation:
External stream is connected to input.harbor and while it's still
connected, I restarted liquidsoap.
When I do that, liquidsoap process is not getting terminated because it's
logging all those "Buffer overrun" messages.
Keep in mined that it's logging what has happened in the past( see the log
timestamp ).
Here is the part of code where I call input.harbor:
def append_master_dj_input(master_harbor_input_port,
master_harbor_input_mount_point, s) =
if master_harbor_input_port != 0 and master_harbor_input_mount_point !=
"" then
master_dj = input.harbor(master_harbor_input_mount_point,
port=master_harbor_input_port, auth=check_master_dj_client,
buffer=0.5,max=15.)
ignore(output.dummy(master_dj, fallible=true))
stopable_master_dj = switch(track_sensitive=false,
transitions=[transition], [({!master_dj_enabled},master_dj)])
fallback(track_sensitive=false, [stopable_master_dj, s])
else
s
end
end
Am I doing something wrong?
Thank you in advance!
