[jira] [Commented] (GEODE-6566) CI failure:
MemberMBeanAttributesDUnitTest testReplRegionAttributes failed with suspect
string
[ https://issues.apache.org/jira/browse/GEODE-6566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16803131#comment-16803131 ]
Barry Oglesby commented on GEODE-6566:
--------------------------------------
Normally, SampleCollector.sample is only invoked by the StatSampler thread. It is the only one that iterates the resourceInstMap.
In this test, that thread is running normally. In addition, the test calls SampleCollector.sample. This now means two threads are executing that method and potentially iterating the resourceInstMap simultaneously.
This is the normal StatSampler thread:
