As you can see, two redirectors started. Now is 1:53 AM. Activity is
zero over 15 minutes.

Configuration is:

url_rewrite_program /usr/local/bin/squidGuard -c
/usr/local/squidGuard/squidGuard.conf
url_rewrite_children 100 startup=0 idle=1 concurrency=0

I.e, second process must be down, correct? Idle=1, so, only one
redirector process must remains.

But we seen two redirectors. One of them is completely idle.

Look, activity is gone:
