Re: [squid-users] Internal dns seems to quit

It shouldn't do! Are you sure you're not hitting swap or something?

It only affected a couple internal servers in the morning but by afternoon google would not come up, msn continued to work. nslookups on the box to the nameservers in squid.conf worked fine. In the Cache manager -> internal dns stats, the queue grew quite big. I installed the caching nameserver package and modified the config to use bind on the local machine, this did not fix it. I ended up restarting squid (loosing 690,000 or so objects in memory). I really do not want to cron a restart, I assume that squid should keep running without these kind of problems.
