Re: Apache loadbalancer with tomcat 6

I have checked 503 error comes in apache access logs while apache error logs show below error.

[Tue May 25 05:06:02 2010] [error] (70007)The timeout specified has expired: proxy: AJP: attempt to connect to 10.10.1.130:8009 (77.66.1.130) failed

Request is not reaching tomcat as nothing comes in tomcat logs. only 503 error in Apache logs

Is the request actually reaching the Tomcat server?  When using a proxy the error from the end point server will also appear in Apache logs as if Apache is misconfigured when in reality the 503 may be coming from Tomcat because of a misconfiguration there.

Check both logs and see if the request is reaching Tomcat.  It may point to more details on the issue.
