Apache 2.2.13 and later ssl vhosts
Since Apache 2.2.13 it is manditory to supply certificate for every ssl vhost you have.
This is rather useful for future tech like server name identification.
Your error messages might say:
Damn I forgot .. well some examples 
insert them. .
The ssl vhost for thejinx.nl has this for example:
SSLEngine on
SSLCertificateFile "/home/jinx/ssl.crt/server.crt"
SSLCertificateKeyFile "/home/jinx/ssl.crt/server.pem"
Hope this helps in any way, shape or form.
Apache 2.2.14 adds better error logging. Havn't tried it but it would have ben rather handy. . .
