You should ensure that your SP's copy of the MIT metadata is kept up to date. The current metadata is available in http://web.mit.edu.ezproxyberklee.flo.org/touchstone/shibboleth/config/metadata/MIT-metadata.xml.
The easiest way to maintain the metadata is via a cron job which runs a script to download and install the latest metadata. A sample of such a script is available in http://web.mit.edu.ezproxyberklee.flo.org/touchstone/shibboleth/config/metadata/update-metadata.sh-example.
The Shibboleth SP software detects and loads the updated metadata automatically; there is no need to restart the web server or shibd.
