Few question for subdomain, Suspension Page..


Dec 13, 2002

I have a RH7.3 with WHM/Cpanel.
I have sevral questions please help me out~~

1. After I create subdomain such as sub.mydomain.com, then wait few hours but, it's not working.
then reboot system, it works.
Whenever I create sub-domain, I reboot system.
Is that normal?

2. I tried modify Suspension Page, default page was already coded. then I just click the save button, but, the page keep displaying 404 page.
How do I do?

3. Since(month ago) I had dedicated server, the server was down once per 7-10days. hosting company keep saying network is OK.
they said check the mem, logs file. but, I don't know what exact problem.
When I see....CPU/Memory/MySQL Usage in WHM.
I got this after reboot system when server was down.

Top Process %CPU 43.0 /usr/bin/perl /usr/bin/mrtg /etc/mrtg/mrtg.cfg
Top Process %CPU 37.0 /usr/bin/perl /usr/bin/mrtg /etc/mrtg/mrtg.cfg
Top Process %CPU 36.0 /usr/bin/perl /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Does anyone knows about this, please help me~~
