since I have installed W3 Total Cache I constantly get "Network unreachable" errors for ONLY about 3-4 random pages on a domain per day. This is unacceptable and I need to solve it even if it's only 3-4 pages.
The only error I see in /var/log/messages is
printk: 2 messages suppressed.
And then when I restarted "named" (I rarely do) I get the message
**network unreachable resolving '18.104.22.168.in-addr.arpa/PTR/IN':** 2001:610:240:0:53::193#53: 1 Time(s)
Do you think the problem is related to the installation of W3 Total Cache or could it be because I started named without adding ""OPTIONS="-4"" and therefore allowing IPv6
I heard Google is already using IPv6
I am very grateful for any response, because I no longer have any idea what I could do.
