Concerning the nested pages: have a look at the worker attribute
recovery_options on

http://tomcat.apache.org/connectors-doc/reference/workers.html

You might like to set this to "3" or "7".

Concerning tc-native: you might try version 1.1.10, which is available
as a separate download. Are there aditional log messages in the jk log?

Regards,

Rainer
