Jeff Jirsa commented on CASSANDRA-10615:
----------------------------------------
JVM OOM was one of the canonical risks of enabling the row cache older versions
of C* before the row cache was made more like a query cache in CASSANDRA-5357.
In 2.1 and newer, options have been added to control how many rows per
partition could be cached ( {{rows_per_partition_to_cache}} ) - were/are you
using the defaults? Do you have the serialized cache files saved?
> Large partition plus row cache causes JVM OutOfMemory Error

> Key: CASSANDRA-10615
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10615
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Cassandra 2.1.8.621
> Reporter: Michael Perrone
>
> Found on multiple nodes of cluster, restarting C* resulted in hung startup
> process, nodes never came up to Up Joining, but would hang until OOM. The
> work-around is to disable row cache.
