> Key: WICKET-6035
> URL: https://issues.apache.org/jira/browse/WICKET-6035
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 7.1.0
> Environment: Jetty 9.3.5, F5 load balancer
> Reporter: Ryan Martin
> Priority: Minor
>
> We've encountered what appears to be an infinite loop leading to a java.lang.StackOverflowError in Wicket 7.1 when a Wicket request is guided to the wrong server by our load balancer. We inadvertently set the load balancer affinity timeout to 3 minutes, while the page expiration was set to 10 minutes. Most of the errors caused by this were fairly routine "ComponentNotFound" exceptions, as one would expect when a Wicket request goes to the wrong server. However, the StackOverflowError was more alarming.

> We haven't been able to reproduce in a quickstart yet, but we verified that the issue arises when the load balancer affinity fails, and goes away when we increase the timeout or drop back to a single server.
