Hello,
today I was looking through some logfiles and I saw something weird. It seems that there are some kernel errors present. To me it looks like squid is the cause of it but I could be wrong. I don't see any other problem and it seems all functionality is still there. Can anyone tell me if I'm right about this and has someone this experienced to?
This is what I see in /var/log/messages
