Hi

you would probably better send to users at shibboleth.net<mailto:users at shibboleth.net>  (which I add in copie)
could you elaborate more
- shibboleth-idp version
- java version
- tomcat version and httpd (if in front / reverse-proxy for TLS ?)
- context (it happened after which action:  update, restart , change config ...)
- the log you show us, are tomcat logs, apache, idp-process ?

thanks

jehan .
