--------------------------------------------
Summary: OOM in Ref#GlobalState
Key: CASSANDRA-10548
URL: https://issues.apache.org/jira/browse/CASSANDRA-10548
Project: Cassandra
Issue Type: Bug
Reporter: Maxim Podkolzine
Attachments: Screenshot.png
Cassandra eats up all memory (at one time 24Gb) and crashes with OOM.
I was able to analyze one instance of hprof and concluded that ~3Gb were
referenced by GlobalState instances, mostly ConcurrentLinkedQueues (see the
details in screenshot attached). I can provide the hprof if necessary.
I noticed that in 2.2 the source code changed in this place. Can you confirm
it's better in 2.2 in terms of memory management?
