Re: Proxy Error

["Parag Dhanuka" <parag.dhanuka@xxxxxxxxx>]

Please help someone... The problem is happening every 3 hrs on a live server :(.... I have writen some script to handle this but cannot really sleep till this is fix....

Besides I also tried connecting locally to the tomcat instance using wget localhost:8091 and interestingly the wget just hung without any response from tomcat.... Is this some weird tomcat issue which I cannot look into.... It is not tht my instance is heavily loaded as it happened also at a time when traffic was really very low.... :(

I did a netstat -n and it seems that I am always having arnd 300-400 connections to the port on which tomcat is listening to the proxy

Hi all,,

I am using an apache server to act as a load balancer to my tomcat server...

I am using reverse proxy for doing this..
The major lines of change in my http conf are these

<IfModule mod_proxy.c>
ProxyRequests Off

<Proxy *>
    Order deny,allow
    Deny from all
    Allow from all
    SetEnv force-proxy-request-1.0 1
    SetEnv proxy-nokeepalive 1
</Proxy>

ProxyPass         /blah http://localhost:8090/blah
ProxyPassReverse  /blah http://localhost:8090/blah

ProxyPass         /blah http://localhost:8091/blah
ProxyPassReverse  /blah http://localhost:8091/blah


My tomcat server conf has this line added with other appropriate changes

    <Connector className="org.apache.catalina.connector.http.HttpConnector" port="8091"
               maxKeepAliveRequests="1" protocol="HTTP/1.1"
               proxyPort="80"/>


Now I am getting this error in my server logs which I have no idea as to how to fix

[Sun Apr 20 03:35:57 2008] [error] [client 66.249.85.88] proxy: error reading status line from remote server localhost
[Sun Apr 20 03:35:57 2008] [error] [client 66.249.85.88] proxy: Error reading from remote server returned by blah

As soon as this error comes soon I am bombarded with errors like
(111)Connection refused: proxy: HTTP: attempt to connect to 127.0.0.1:8091 (localhost) failed

All tht I get on my webserver is a 500 response.... I am lost.... Please help....I gooogled a lot and added
    SetEnv force-proxy-request-1.0 1
    SetEnv proxy-nokeepalive 1

and also removed keepaliverequest from tomcat. but still I soon ended up getting into this problem :(
