Hi Lilian, > The effect was exactly the same : squid stop every hour. Are you sure that no cron job is running which terminates squid? Could you please check * /etc/crontab * /etc/cron.hourly/ and do a "crontab -l" as root? If there is anything running, please check what exactly that job is doing. Maybe that's the reason.
