We're using Wildlfy v15.0.1 and external traffic reaches Wildfly app servers via a load balancer, lately we are seeing 502 gateway timeout for certain calls. One of the recommendation from load balancer support team is to enable keep-alive settings at the app server level to match the load balancer, we have a 15 min idle time out set on load balancer. It would be great if anyone has any insights or recommendations on this topic. We basically wish to match idle time on Wildfly to whats configured in our load balancer.
I can across the link below, please confirm if its applicable to Wildfly v15.0.1
Thanks for your help in advance.
