Or debug_options ALL,1 47,0 if you want level-1 messages from other
Squid components.

Just to add to that. In a way it is a sign of trouble if you have a lot
of them for a very long time. Squid is unable to serve cached content
out of the cache_dir for the duration of rebuilds. As long as it is
displaying Squid is operating at somewhat lower than optimal performance.
 However on large cache_dir a re-scan can take a long time. It is one of
the annoying things we have been seeking to fix for quite some time.
