Hi,

 Apache will log the server reached MaxClients setting... message 
 only once and then never again until the next restart. Maybe this is 
 the problem you are seeing?

Hmmm... On the morning I found the problem, there was a scan that made
me hit 'MaxClients'. While testing it, I did only reloads, and no
restart, of apache.

I just tested it, and indeed, after a fresh restart it does display the
server reached MaxClients setting... message when hitting too many
proxy requests.

Is there a configuration to make apache display this message more
regularly, e.g every 300 seconds?

thanks,

Winfried

Bug#506763: apache2: mod_proxy does not log an error when it hits MaxClients

2008-11-24 Thread Winfried Tilanus
Package: apache2
Severity: normal

I am using apache2-mpm-prefork (2.2.3-4+etch6), with an proxy configured 
like this:

Proxy *
   Order deny,allow
   Allow from all
/Proxy

ProxyRequests Off
ProxyPass /3/ http://miepie.tilanus.com:80/3/
ProxyPassReverse /3/ http://miepie.tilanus.com:80/3/
ProxyPass /http-bind/ http://miepie.tilanus.com:5280/http-bind/
ProxyPassReverse /http-bind/ http://miepie.tilanus.com:5280/http-bind/

When the amount of connections to proxy exceeds the the amount 
configured by the MaxClients directive in the apache2.conf, apache 
doesn't relay the connections anymore. This happens silently. In order 
to ease troubleshooting, it is desireable that apache2 also warns when 
it hits the MaxClients while proxying requests.

Thanks for looking into this!

Winfried
