you can add logging like this,<div><br></div><div>log.warn(">>>>> Got data from host %s:%d <<<<<<" % (host, port))<br><br>If you put this line in mediacontrol.py just above line 130 (where the error is reported in syslog) and then restart the service then it will print this warning for each call and give us some hint of the problem when it happens.</div>
