apache is going really slow (and restarting it is the only thing that helps)

hey all i've been having some problems the last few months with my server/apache getting really slow (pages loading slow) and the only way i can fix it is to restart apache which is quite annoying and is not fixing the problem but it gets to the point where pages are almost not loading so i have to keep restarting apache but after 2mins it'll be slow again and once again i'll have to restart apache

and here's my apache2.conf

right back to the problem i first thought it was some kind of DOS/DDOS attack so i ran the following commands:

the first shows a bunch of ip's and there connections but there's nothing to weird as there is only a few ip's that have over 20-30 with the rest having very few

the second command shows the total connections and again nothing to odd about the number (150-250 ish)

the third is for SYN but that's always been low on testing it like 1-10

i think all this is quite normal (although i might be wrong) so i'm now quite stumped as to what the problem is and how to go about fixing it

server specs/info:

amd dual core 2.5ghz, 4gb ram, 2x 300gb hard drives etc

ubuntu 8.10 server (dedicated) with apache2-prefork/php5/mysql, webmin/ispconfig

please advise thanks

note: i forgot to say that memory usage is a little higher then normal (500mb-700mb compared to 250mb-300mb - but goes back to normal after restarting apache) and the load is also a little high but always under 1 (also note my server is on a 100mbits port and i can easily push 100mbits 24/7 with no problems at all so it's not bandwidth)

 

what your maxclient value?

 

maxclient value = 150

 

Hello,

Need to compile apache . Do you have cPanel installed ?

 

why would i need to install apache? and no i don't use cpanel i use webmin/ssh

 

just change the vlaue to 200 or 250 and the restart the apache and check it

it may work for you some time

 

i've only just changed it from a higher value which helped so i'm not making it higher

 

I have been battling this for the last couple of months as well

I have pushed my max clients to 1000 and it hasnt helped

I have tried nginx (it didnt work for me - but it might for you)

I am wondering if Apache can process more than one request at a time - I have 900 tasks in the list - processing 1 - 899 sleeping - sever load is under 1 - memory use is OK, CPUs are 98% idle, and yet I have page load issues and a very slow site

I hope someone can help you - because I bet it will help me

Good Lucl
