Shibboleth.Listener shutdown after XMLTooling.StorageService purge

[Janemarie Duh]

We are running Shib SP v2.5.0 on a RHEL6 6.3 server for an instance of
Moodle.

Today at around 12:30, users stopped being able to authenticate to the
service. When I grepped the processes, I saw that shibd was no longer
running. Shibd.log[0] showed that the storage service purged some
records and that the Shibboleth listener shut down the worker thread. I
restarted shibd. A load spike on the server occurred around this same time.

I obviously need to prevent this from happening again since this is a
high-profile/use system. What are the records that the storage service
purges? Are they transaction records or session information? We are
using the default storage service settings.

Thanks for any leads or advice on what may have caused this shutdown.
