Subject RE: [users@httpd] General question - Apache server-status page
Date Mon, 13 Jun 2011 19:01:21 GMT
My problem is as it stands, the loads are too high already, at peek times
our Dual Quad Core Xeons with 18 gigs of ram go as high as 100.00 and this
is with a max clients of 600. We do use memcache and eaccelerator.


I mean I should have been more clear. I do know what the W and C are I was
just wondering why there would only W and Cs.. sorry for the confusion


When the server is at a load of 100 we still have 2 to 3 gigs of ram to
spare and there is never any swapping.


I just do not think that the problem is server capacity, it seems to be
something else I think, but not sure what?


In a top I see every couple of mins on all servers this.

22498 apache    15   0     0    0    0 Z  0.3  0.0   0:45.98 httpd <defunct>


Right now all our server are at .

That your server(s) is/are swamped.

Consider adding more worker threads/processes.

If I see all the slots filled with W and C only, what would that indicate,
this is during high traffic times..


We are on Centos 64 bit with Apache 2.2,  and have 6 webservers behind
