Clustering w/ TC 3.5.3 (was Re: Clustering with Terracotta 3.6)

Hi Liam,

Yes, I do. I've no idea if it's TC-related or not. Since it's warning about potential memory leaks
caused by the webapp being stopped, I've always taken the line that it can't possibly matter,
since I'm actually stopping the JVM. I've not had any production problems with TC (except the
occasional split-brain when our network group upgrade routers and partition the two IDPs).

Possibly unrelated, but buried in your log is:

*sys-package-mgr*: can't create package cache dir, '/var/tomcat/work/Catalina/localhost/idp/WEB-INF/lib/jython-2.2.1.jar/cachedir/packages'

You might want to make sure Tomcat can write there, and anywhere else in Tomcat's work
directory.
