Apache server always down and service status unavailable

[tefon]

I have a problem with my server, sometimes web pages are unavailable for 1-2-3 minutes not to much and the command 'service httpd status' does not return anything but after that when the website come back alive the command returns. Notice than when httpd looks to be down, FTP/SSH/cPanel and WHM are fully working, can operate them perfectly.

I appreciate any help to solve this issue.

Thanks !

EDIT (a very strange problem)
For example : I have 3 web sites in server and site adress A B C

A : Down
B : Down
C : Working..
Cpanel, Ftp, SSH : Working..

and 2-3 minuter after,
A : Working..
B : Working..
C : Down
Cpanel, Ftp, SSH : Working..

and 2-3 minuter after,
A : Working..
B : Working..
C : Working..
Cpanel, Ftp, SSH : Working..

Please help me, urgently.

Thank you
