During this problem I am not able to telnet 8090 on server too.

This problem get solved once I restart MySql.

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
