Attila Doroszlai commented on HDDS-3215:
----------------------------------------

Can be reproduced by adding 10 sec sleep before the assert in 
{{TestSCMNodeMetrics.testNodeReportProcessing}}.  The problem is that 
{{NodeReportHandler}} might process a report in the background, so the count is 
more than the expected.

> Intermittent failure in TestSCMNodeMetrics
