We have deployed a war file on tomcat6. We are facing a error
[Sat May 17 12:26:48 2014] [error] (110)Connection timed out: proxy: HTTP: attempt to connect to 127.0.0.1:8090 (127.0.0.1) failed

During this problem I am not able to telnet 8090 on server too.
This problem get solved once I restart MySql.
Help appreciated from expert.
Thanks Ranjeet Ranjan

The solution to this is to add the "retry=0" parameter to your ProxyPass directives in your Apache HTTP server virtual host configurations so that it doesn't wait the default 60 seconds to retry.
E.g.
ProxyPass / http://backendserver:8080/ retry=0

You can use
setsebool -P httpd_can_network_connect on

Perhaps, the problem is the network. For example. If the IP of the webserver is 192.168.1.1 and the other webserver is 192.168.0.100, the servers are in a different subnet range. – Matias Colli Consultor IT
