Which takes us back to my comment of almost a week ago. You have
development mode enabled which retains the pageNodes for improved error
messages. Disable development mode and the memory usage should fall.
I don't recall any changes to this code bewteen 7.0.8 and 7.0.10 but to
be sure, I have double checked that disabling development mode does
indeed have the desired effect.
To fix this:
- edit $CATALINA_BASE/conf/web.xml
- find the definition for the servlet named "jsp"
- add the following init parameter
<init-param>
<param-name>development</param-name>
<param-value>false</param-value>
</init-param>
