Logout plus non-member on list == no real support from me, beyond a cursory glance. Logout is a bright line.

That's wrong, it should be shibboleth.ClientSessionStorageService. Whether it's fatal or not, I doubt it.

The IdP only tracks one session per SP per IdP session. The log suggests you have the same SP involved in two separate logins or logouts from the same user in the same session and either the second login overwrote the first but the logout request refers to the first, or the second logout came in after an earlier one that worked.
