connection to a Web server, not the more closed

help
 
Hello,

So i need help, plz .

You need more informations ??

falko 5th February 2009 21:42

I'm not sure what's happening... :(

eterzella 6th February 2009 13:00

I did the following test, the shut Ultramonkeys.

And even then my apache continued with the same problem. Thought
it was problem with the connections that were getting in
timewait. This time there are no more connection and even then he
not respond to web requests.

I try to "TOP" and not answered. I believe it may be some
something related to memory.

What do you think? Have you ever seen the "TOP" stop
answer the charge?
