I see reference to something similar on cas-user from some time ago, but the
thread appears (to my untrained eye) marginally conclusive other than calling
it a likely deadlock.
Should this be something of concern? I saw a generic client mail shortly
thereafter about an "Internal Server Error" but it doesn't identify whether it
was SSO or something else.
Thanks.
Tom.
