> Key: CASSANDRA-17795
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17795
> Project: Cassandra
> Issue Type: Improvement
> Components: Local/Other
> Reporter: Josh McKenzie
> Assignee: Josh McKenzie
> Priority: Normal
>
> We should add the optional hot-proppable / in .yaml ability to collect a heap
> dump when any uncaught exception is handled by the {{JVMStabilityInspector}},
> assuming it's not an OOM or something that marks the JVM unstable.
> This has come in handy in a variety of prod debugging scenarios and would be
> good to have baked into the DB proper for operators.
