Hi Helin, Is this the correct fix? IMHO, if this is a problem, then we should surely not be hiding and ignoring the error. If it's not a problem, then the log level should be reduced to a lower level, e.g. INFO or NOTICE. Alternatively, this code could be modified to only print an error once for each unsupported request type. Ideally both solutions should be used, I think. I'm not sure I like setting the default log level to just show EMERG messages. Regards, /Bruce
