This is most likely a server issue on an overloaded shared server. Ask your hosting company to move your account to another server and see if the problem continues.

not shared , dedicated , and that is what is bothering me ,
CentOS 5
Uplink Port Speeds 100MBPS

If you are on a dedicated server I would advise that you request server optimization help by starting a thread in the Server Configuration forum supplying the information requested in this thread:

Since this is not an official service the response may not be as fast as you are used to in the ticket system.

thank you much , will do

that thread is closed and is 4 years old

[Wayne Luke]

Yes.. If you read the thread, it tells you what information you need to provide. You then create a new thread with that information in the same forum.
