Sun Java System Application Server 9.1 Troubleshooting Guide

Is the Load Balancer Timeout Correct?


When configuring the response-timeout-in-seconds property in the loadbalancer.xml file, you must take into account the maximum timeouts for all the applications that are running. If the response timeout it is set to a very low value, numerous in-flight requests will fail because the load balancer will not wait long enough for the Application Server to respond to the request.

Conversely, setting the response timeout to an inordinately large value will result in requests being queued to an instance that has stopped responding, resulting in numerous failed requests.


Set the response-timeout-in-seconds value to the maximum response time of all the applications.
