-----------------------------------------------
Summary: Limit number of OOM heap dumps to avoid full disk issue
Key: CASSANDRA-20457
URL: https://issues.apache.org/jira/browse/CASSANDRA-20457
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Dmitry Konstantinov
Assignee: Dmitry Konstantinov
We can add the following protective logic to our startup scripts for Cassandra:
* check the directory is used for heap dumps
* if the number of existing heap dumps more than a threshold configured in an
env variable then remove the oldest one
It allows to avoid a case when we have a periodic OOM due to some issue and
eventually kill ourselves due to lack of disk space consumed by heap dumps.
