After investigation, we found that threads are stuck on the sum() in streaminghistogram class. Those are jmx threads that working on expose getTombStoneRatio metrics (since jmx is kicked off every 3 seconds, there is a chance that multiple jmx thread is access streaminghistogram at the same time). After further investigation, we find that the optimization in CASSANDRA-13038 led to a spool flush every time when we call sum(). Since TreeMap is not thread safe, threads will be stuck when multiple threads visit sum() at the same time. There are two approaches to solve this issue. The first one is to add a lock to the flush in sum() which will introduce some extra overhead to streaminghistogram. The second one is to avoid streaminghistogram to be access by multiple threads. For our specific case, is to remove the metrics we added. was: optimization in CASSANDRA-13038 led to a spool flush every time when we call sum. Since TreeMap is not thread safe, threads will be stuck when multiple threads visit sum() at the same time, and finally 100% cpu is stuck in that function.
