Timeout or something?

[Nate Klingenstein]

SWAG:

It sounds like the SP is set to automatically protect a resource, and the session cookie for that resource is timing out.  The original invocation of Shibboleth included an entityID parameter of some sort somewhere.

On session expiration(modulated by the Sessions element's "lifetime" and "timeout" timeouts)

https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPSessions

your SP is trying to restablish a new session for that user, but it doesn't have the entityID parameter supplied to it and there's some default in place somewhere that goes to idp.example.org, probably in your SSO element in shibboleth2.xml.
