server.log overflow - /var/log/sqeezeboxserver/scanner.log fills /var

Hello everybody,

LMS leads to log overflow: After some hours of use, there is a several GB big scanner.log file in /var/log/squeezeboxserver/scanner.log
The following lines shows the beginning - the last error message is repeated infinitely...
