> 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.
