> The {{TsTabletManagerITest.TestTableStats}} test scenario fails from time to time, at least in TSAN builds.  I'm not sure whether that's something related to the test itself, an issue related to stack collection, or a bug somewhere else.  When it fails, it reports something like below.  The full log is attached.
