Your access logs should show the individual SAMLRequest's generated by
Google; if it's rejecting your assertions in some automated way you
should see a new SAMLRequest each time.  If it's the same request over
and over, one might infer a more local issue (not definitively mind you;
just much more likely) [ehcache issue, browser configuration, etc.].

Has anyone talked with your end users who're triggering these events
about what they experienced?
