our virtual server involved
We do not know the reason of our disconnection between httpd and tomcat 6.0.18
via ajp, but we recognize that we have load of files upload and dwonload for
the great amount of files in the liferay portal at the document library porlet,
we describe our scenario
scenario :
1)
we've got liferay-5.2ee bundle tomcat running over the redhat under next
server.xml ajp connector configuration:
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009"
acceptCount="1024"
connectionTimeout="20000"
emptySessionPath="true"
maxThreads="600"
protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" />
2)
we've got http running via prefork mpm with the next configuration:
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 1024
MaxClients 1024
MaxRequestsPerChild 4000
</IfModule>
3) we've got the next proxypass configuration between httpd and liferay:
ProxyPass /educacion/colabora/temas ajp://localhost:8009
ProxyPassReverse /educacion/colabora/temas ajp://localhost:8009
ProxyPass /html ajp://localhost:8009/educacion/colabora/html
ProxyPassReverse /html ajp://localhost:8009/educacion/colabora/html
ProxyPass /image http://localhost:8080/educacion/colabora/image
ProxyPassReverse /image http://localhost:8080/educacion/colabora/image
ProxyPass /educacion/colabora ajp://localhost:8009/educacion/colabora
ProxyPassReverse /educacion/colabora ajp://localhost:8009/educacion/colabora
Actions:
1) httpd in debug mode in error.log with the next output:
