Ilya Lantukh commented on IGNITE-10437:
---------------------------------------
[~SomeFire], It seems to me that your patch doesn't solve the issue, but just
reduces it's probability. I would prefer to re-write this test (and
GridCacheTestStore if necessary) to ensure that overflow always happens. For
example, you can insert CyclicBarrier or CountDownLatch into
GridCacheTestStore.write method to make all Flusher threads stuck, or you can
put data in test in a *while* loop until overflow happens.
> GridCacheWriteBehindStoreMultithreadedSelfTest.testFlushFromTheSameThreadWithCoalescing
> is flaky
