If it's a busy server, you may be running out of TCP connections...
If PHP can't open ANY connection at all, it can't do a DNS lookup, and
it would fail very fast, as it's hitting an OS limit/cap on the number
of connections and not even getting to try to talk to the Internet.

DNS records are failing to lookup the domain name for you...
Maybe just put the URL back into a queue to try later.
You should also toy with nslookup or dig from the command line and see
if you can get it to fail as often.

I think I've solved this. I found a problem with resolv.conf that contained
some outdated DNS servers. After changing that and rebooting the server it
seems to be working. It didn't seem to work after just changing
