Greetings.
I am having some weird error when starting tomcat - the exception in the
logs is:
WARNING: Error registering contexts

This results in none of the 49 contexts (hosts) to start correctly (or
rather to be available). When I request one of the hosts it returns a HTTP
400 - Bad Request!
If I retart Tomcat enough times - it does come up eventually!
The only thing I have added is a HTTPS Coyote Connector - using a PKCS12
keystore for a cert for ONE of the contexts (hosts)! Nothing else has
changed - and it has been running for a fairly long time!
Any ideas?
Carl
