Things to check:
. after 'start' does /var/run/dynip.pid exist while it's running??
. if so, does it contain the same PID as 'ps ax' shows for dynip?
. does 'ps ax' show a different PID for the subshell, if there is one?
. Does /var/run/dynip.pid still exist after running 'stop'?
i.e. is the PID needed for kill the same as that in /var/run/dynip.pid?

I've very little knowledge of the detailed behaviour of the rc system.
Let's see how the above questions might inform before speculating ..
cheers, Ian
