We are doing bulk REST operation, that lasts for more than 15 mins , we are using wildfly undertow load balancer. We see that load balancer is retriggering the rest call internally after 11 mins even though original REST call have not completed yet. could anyone please suggest where we are going wrong? We have frontend : undertow load balancer and backend : 3 nodes of widlfy we are using CPU metric for load sharing.
When we triggered bulk update from front-end , we observed below logs:
Initial request went to IVM-0 (i.e. this is wildlfy node)
