How to clean the SP after "shibsp::ConfigurationException"

[Rainer Hoerbe]

I ran into a state where the SP is stuck with a shibsp::ConfigurationException at (https://samlecho2.hoerbe.at/secure/test.php) . Session initiator did not handle request for a new session, check configuration. 

I did not change the configuration. The sequence to arrive at this state is to send an AuthnRequest, wait for a few minutes, and reload the Login-screen at the browser (SP 2.5.0, IdP 2.3.3). 

The problem is that the SP remains in this state even across restarts. But it did reset itself over the lunch break. Is there a kind of clean-flush-purge -f command to have that effect immediately?
