[users@httpd] Apache performance server reached MaxClients setting

Gamesnel - Piethein Strengholt <piethein@xxxxxxxxxxx> · Thu, 02 Jun 2005 08:50:25 +0200

I have a plesk (7.5.2 box) running with Redhat 9. This machine (Pentium 

4 1024 mhz) was running fine for quite a long time. This week one of my 

sites became very populair and this gives me some troubles. The apache 

server stops to work and I need to restart it within every 10 minutes. 

Then apache is up and after 10 minutes its down again. The server log 

said this:

[error] server reached MaxClients setting, consider raising the 

MaxClients setting

So I changed the MaxClients from 100 to 256.

This will increase the dying time from 10 minutes till 20 minutes but 

does not solve the problem. When I check the apache status I see this:

//etc/init.d/httpd status

httpd (pid 5073 5072 5071 5070 5069 5068 5067 5065 5064 5063 5062 5061 

5060 5059 5058 5057 5056 5055 5054 5053 5052 5051 5050 5049 5048 5034 

5033 5032 5031 5030 5029 5028 5027 5026 5025 5024 5023 5022 5021 5019 

5018 5010 5009 5008 5007 5006 5004 5003 5002 4998 4997 4995 4994 4991 

4990 4988 4953 4952 4951 4950 4949 4947 4946 4945 4944 4943 4942 4941 

4940 4939 4938 4937 4936 4935 4934 4933 4932 4930 4929 4928 4927 4926 

4925 4924 4923 4922 4921 etc etc etc/

This is my current httpd.conf:

/KeepAlive Off
MaxKeepAliveRequests 100
KeepAliveTimeout 15

<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
MaxClients 256
MaxRequestsPerChild 1000
</IfModule>

<IfModule worker.c>
StartServers 2
MaxClients 256
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>

<IfModule perchild.c>
NumServers 5
StartThreads 5
MinSpareThreads 5
MaxSpareThreads 10
MaxThreadsPerChild 20
MaxRequestsPerChild 0
</IfModule>/

Please let me know how I can solve this problem!
