Subject RE: [users@httpd] MaxClients

Hi Paulo,

MaxClients 256 should be able to handle a lot of traffic, especially with KeepAlive turned
off. Is this a high volume site?

My first thought would be that transactions are taking a long time to complete, probably because
of some back-end service slowdown, which ties up connections until you reach 256, at which
point the server queues connections. It could also happen if you're service large files to
people with slow connections.

Beyond that, you could increase MaxClients, but if you're on UNIX then you'll have to edit
the source code and recompile, as the default limit is 256.

Mark

Hi all,

I have been received a message in my apache error log:

"[Wed Jun 23 09:36:07 2004] [error] server reached MaxClients setting,
consider raising the MaxClients setting"

After that my Web Server isn't responding for user's requests and I must
stop/start Apache to bring up the service.

Follow are the part of my httpd.conf talking about performance:

Timeout 300
KeepAlive Off
MaxKeepAliveRequests 100
KeepAliveTimeout 15
MinSpareServers 100
MaxSpareServers 300
StartServers 100
MaxClients 256
MaxRequestsPerChild 10000
Listen 8000
Listen 80

The Apache Version is 1.3.24.

May somebody help me, please?

Thanks a lot.
