On multiple occasions our SSO application started failing with the below exception and gets resolved by app pool recycle.

Exception Type: ComponentSpace.SAML2.Exceptions.SAMLConfigurationException
Exception: An X.509 certificate for the partner service provider *** hasn’t been configured.
Stack Trace:

We’re using SAML configuration file to define Partner Service Provider.
<PartnerServiceProvider

I’d like to see the certificate failing to load as well as successfully loading after recycling the app pool.
Thanks.
