Robert Stupp commented on CASSANDRA-9861:
-----------------------------------------
There's {{org.hyperic.sigar.Sigar#getPid}} to get the process ID.
Maybe we should use {{jmap}} from {{System.getProperty("java.home") +
"/bin/jmap"}} (resp. {{jmap.exe}}) and only use {{map}}/{{jmap.exe}} as a
fallback.
> When forcibly exiting due to OOM, we should produce a heap dump

> CASSANDRA-7507 introduced earlier termination on encountering an OOM, due to
> lack of certainty about system state. However a side effect is that we never
> produce heap dumps on OOM. We should ideally try to produce one forcibly
> before exiting.
