cPanel gone crazy and quering apache every second

[sehh]

One of the cPanel processes (maybe chkservd?) is hitting my apache hard with GET requests, once every second! This started after the level 2 upgrade of cPanel v11 STABLE.

take a look at this:

Can someone please help trace which process is doing that?

 

[sehh]

nobody has any ideas why this is happening?

nobody has any ideas why this is happening?

I'd recommend submitting a support ticket regarding this issue:http://tickets.cpanel.net/submit

Note, chkservd usually only checks services once every 8 minutes.

 

[sehh]

I've stopped "chkservd" and the log file continues to grow with those "GET / HTTP/1.0" requests.

Is there another cPanel component which performs such a GET request?

Not that I am aware of.

 

[sehh]

I found out what the problem is:

EA3 adds the following configuration lines:

NameVirtualHost *

and...

<VirtualHost *>
    ServerName server.domain.com
    DocumentRoot /usr/local/apache/htdocs
    ServerAdmin [email protected]
</VirtualHost>

the problem is the asterisk, which causes the dummy_connection function to open and close a connection every second.

if the above lines are commented out, then the dummy connection stops.

PS:
this is with apache 2.2.

I guess also i have the same problem, i just caught it at apache status, last records were like that

So do i need to comment out all 4 rows you said?

 

[sehh]

Yes, thats correct, you have to comment out all 4 lines.

 

[bonjurkes]

now when i start or stop apache it shows this warning

[Fri Dec 21 13:01:35 2007] [warn] NameVirtualHost *:0 has no VirtualHosts

is it ok?

 

[sehh]

I'm sorry, i forgot to mention that you also need to comment out the following line:

NameVirtualHost *

edit: i also edited my solution above to include this line as well.
