Issues with connecting to Jboss server

[Varshini Priya]

Hi

We have an application and it uses apache as the webserver and Jboss as the application server. The communication between the apache and the jboss servers happens via the AJP13 protocol. Recently we are experiencing some issues where the webserver is unable to communicate to the application server. when we checked the jboss appln server, we have monitors in place which indicated that the application server was up and running.But the webserver was unable to communciate to the appln server. we were receiving the below error logs in the webserver

The tomcat that it is connecting to is available in the in the jboss under deploy folder under jboss-web.deployer

we are currently using jboss 4.2.1 as the application server


Can you please help/ provide some guidelines as to where/how I can go about fixing this issue.
