INVOKER fails after webapp recompile

Hi all,
every time I recompile my servlet (targetted at the deployment directory),
org.apache.catalina.INVOKER lists it as unavailable. This is "fixed" by
stopping and starting the tomcat server, but this is far from ideal. Can
someone tell me why this happens and what can be done so that it will
reload the app correctly and launch it, without becoming 503 unavailable?

Under is a dump from reloading one file, I get one of these for each file
in the webapp.

Cheers

Nik
