Yes, cron jobs are present and executed on time (by lines in
service_watcher.log), however that happens to be the same time that my
registrations go away every night.

A simple script on another machine downloads the ls_cache tarball and
checks ls_cache/list.X for the bwctl server long intervals are me not
noticing for a few days

I actually saw the script_watcher patch a day or so ago on another list
and have it applied, so I'll keep an eye out and see if the new version
helps out.

Side Note: the scripts are at http://raharu.usc.edu/git and consist of a
script with code from ls_cache_daemon to fetch the cache and a script to
query for services and projects.  Much like a CLI version of the web
page...
