[Joeybe11]

[config:server:listener] No listener is available for normal virtual host!
2008-03-04 22:40:23.225 ERROR [/usr/local/directadmin/data/users/*****/httpd.conf:304] Listener for xx.xx.xxx.xx:80 is not available!
2008-03-04 22:40:23.227 ERROR [/usr/local/directadmin/data/users/*****/httpd.conf:416] Listener for xx.xx.xxx.xx:443 is not available!
I'm getting these errors, how do I fix these?

I think it's because that IP address is not available on that server.

[Joeybe11]

No, it's available. But my server has been going very slow lately, it will go fast, then it just slows down, and keeps repeating. There is no current network issues either.

check the result of

"iptables -L"

You have rate limit. I don't know it is the root cause or not, but it is definitely a problem of your kernel configuration.

[Joeybe11]

I've removed the SYN rate limit, but websites still load slow. What would you suggest?

I don't know, but what I observed on your server is that, the data stay in TCP send buffer for very long time, so, it is TCP/network problem. You can check that with

netstat -an | grep ESTA

The "Send-Q" value stay the same non-zero value for very long when you experience the "SLOW" problem. Check if you Packet Loss and retransmission is high or not with command

netstat -s

Thanks for your help. I've forwarded your information to my server provider and they're going to take a look.
