             Summary: GMSHealthMonitorJUnitTest.testHMServiceHandlesShutdownRace hangs occasionally
                 Key: GEODE-5465
                 URL: https://issues.apache.org/jira/browse/GEODE-5465
             Project: Geode
          Issue Type: Task
            Reporter: Dan Smith


This test appears to have some sort of race condition that can cause it to hang. It hung in a precheckin run here:

https://concourse.apachegeode-ci.info/teams/main/pipelines/pr-develop/jobs/IntegrationTest/builds/200

I was able to reproduce the hang by running this test 100 times on my laptop. Here's the stack dump from my laptop
