It's normal for your services to disappear from the hLS for a while after the 
service_watcher script runs 
with the  --regular_restart option at 1am. This script actually completely 
removes the database, as
we were having problems with database corruption after a couple days.

However this is not a problem, as all services re-register within an hour, 
and the index service used
to generate global directories (e.g.: 
http://nettest.lbl.gov/toolkit/gui/perfAdmin/directory.cgi 
and https://stats1.es.net/perfSONAR/directorySearch.html) are based on a 
script that runs every 8 hours,
and only removes services that are missing for a full day.
