Session draining on stopped worker won't complete if further requests are made on balancer

Start mod_cluster configuration with at least two workers (with session-draining-strategy=ALWAYS) and one balancer Deploy simple application with simple web.xml defining session timeout: <web-app> <distributable /> <session-config> <session-timeout> 1 </session-timeout> <!-- minutes --> </session-config> </web-app> on each worker Make request on balancer to context created by deployed application and check which worker handled this request Disable this worker /subsystem=modcluster/proxy=default:stop(waittime=0) Check, that contexts on this worker are disabled Make further requests on balancer to the same context Draining will never complete (intermittently)
