Session draining on stopped worker won't complete if further requests are made on balancer ------------------------------------------------------------------------------------------ Key: WFLY-11198 URL: https://issues.jboss.org/browse/WFLY-11198 Project: WildFly Issue Type: Bug Components: mod_cluster Affects Versions: 15.0.0.Beta1 Reporter: Jan Kašík Assignee: Radoslav Husar Priority: Major Attachments: logs.zip When disabling worker with {{/subsystem=modcluster/proxy=default:stop(waittime=0)}}, the contexts are switched to {{disabled}} state. If there no further requests (on the same context which session currently times out) are made on a balancer, session correctly times out, contexts switch to {{stopped}} state and everything is OK. However, when I run same stop operation, wait until contexts are switched into {{disabled}} state and in time in which sessions time out I make more requests on balancer, contexts will never switch to {{stopped}} state and session draining never completes. This happens intermittently (~60% of cases with 10 requests made after {{disabled}} state is in place).
