Hi,
I am using Apache 2.2.16-3 on Debian (2.6.21-1-486 kernel version).
I configured my apache server to serve Zope Requests, Tomcat Requests and
apache document root files
something like the below:
*********************************************************************************************************************************************
<VirtualHost *:80>
ServerName test.com
ServerAlias www.test.com
ServerAdmin webmas...@orgn.com
ServerSignature Off
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
SetEnv proxy-initial-not-pooled 1
DocumentRoot /var/www/
<IfModule mod_rewrite.c>
RewriteEngine On
JKMount /testapp* tomcat
RewriteCond %{REQUEST_URI} !^/testapp # this is application served
from tomcat server
RewriteCond %{REQUEST_URI} !^/sample # this is application served from
Apache DocumentRoot /var/www
RewriteRule ^/(.*)$
http://localhost:8090/VirtualHostBase/http/test.com:80/test/VirtualHostRoot/$1[L,P]
# this is rewrite rule for plone site being the default site at
test.com
<Location />
Order deny,allow
Deny from all
Allow from all
</Location>
</IfModule>
<IfModule mod_proxy.c>
ProxyVia On
# prevent the webserver from beeing used as proxy
<LocationMatch "^[^/]">
Deny from all
</LocationMatch>
</IfModule>
# Removed log file lines and other unimportant lines
</VirtualHost>
*********************************************************************************************************************************************
With this configuration, the all my applications are working fine but with
one problem. The Zope website is becoming slower frequently and later
hanging the complete system after 2 to 3 days. When checking the apache log
files I see the following message repeatedly coming in.
[Wed Jan 04 01:59:26 2012] [error] [client 207.46.13.147] proxy: Error

localhost:8090
On Restarting the system is only resolving the issue.
When checked in zope mailing list and apache mailing list, I see an option
os using
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
I have used them in my config. even though I face this problem frequently.
Could someone help me in identifying the problem or cause of the problem
and way of resolution.
