Bug ID: 64312 Summary: Many memberDisappeared messages are logged on all nodes of the cluster with JDK versions 12 or above, even when system is idle Product: Tomcat 8 Version: 8.5.50 Hardware: PC Status: NEW Severity: normal Priority: P2 Component: Cluster Assignee: dev@tomcat.apache.org Reporter: mahathivavilal...@gmail.com Target Milestone: ---- When a cluster is installed with TOMEE 7.0.7 (uses Tomcat 8.5.50.0) with JDK 12 or above only, for default values of frequency (=500) and dropTime (=3000), many memberDisappeared messages are logged on all nodes of the cluster. This is occuring even when the system is idle. The following messages are seen in the logs: Mar 19, 2020 9:43:56 AM jdk.internal.reflect.DelegatingMethodAccessorImpl invoke INFO: Received memberDisappeared[org.apache.catalina.tribes.membership.MemberImpl[tcp://{10, 18, 88, 143}:4001,{10, 18, 88, 143},4001, alive=1683768, securePort=-1, UDP Port=-1, id={-16 81 -2 100 -1 -27 65 77 -100 123 96 -67 -54 -14 107 84 }, payload={}, command={}, domain={}]] message.
