Kirk Lund updated GEODE-7739: ----------------------------- Fix Version/s: (was: 1.13.0) > JMX managers may fail to federate mbeans for other members > ---------------------------------------------------------- > > Key: GEODE-7739 > URL: https://issues.apache.org/jira/browse/GEODE-7739 > Project: Geode > Issue Type: Bug > Components: jmx > Reporter: Kirk Lund > Assignee: Kirk Lund > Priority: Major > Time Spent: 20m > Remaining Estimate: 0h > > JMX Manager may fail to federate one or more MXBeans for other members > because of a race condition during startup. When ManagementCacheListener is > first constructed, it is in a state that will ignore all callbacks because > the field readyForEvents is false. > ---- > Debugging with JMXMBeanReconnectDUnitTest revealed this bug. > The test starts two locators with jmx manager configured and started. > Locator1 always has all of locator2's mbeans, but locator2 is intermittently > missing the personal mbeans of locator1. > I think this is caused by some sort of race condition in the code that > creates the monitoring regions for other members in locator2. > It's possible that the jmx manager that hits this bug might fail to have > mbeans for servers as well as other locators but I haven't seen a test case > for this scenario. > The exposure of this bug means that a user running more than one locator > might have a locator that is missing one or more mbeans for the cluster. > ---- > Studying the JMX code also reveals the existence of *GEODE-8012*. -- This message was sent by Atlassian Jira (v8.3.4#803005)
