You might also have some gains setting in_memory_compaction_limit_in_mb
to something very low to force Cassandra to use on disk compaction rather
than doing it in memory.
Cool Ben.. thanks I'll add that to my config as well.
Glad that helped. Thanks for reporting back!
No problem, Nate!

Definitely thank you for this advice. After leaving the new Cassandra node
running on the 2GB instance for the past couple of days, I think I've had
ample reason to report complete success in getting it stabilized on that
instance! Here are the changes I've been able to make:
I think
The most important things to note:
- don't include JNA (it needs to lock pages larger than what will be
available)
- turn down threadpools for transports
- turn compaction throughput way down
- make concurrent reads and writes very small
I have used the above run a healthy 5 node clusters

2.1.2 is IMO broken and should not be used for any purpose.
Use 2.1.1 or 2.1.3.

Cool man. Thanks for the info. I just upgraded to 2.1.3. We'll see how that
goes. I can let you know more once it's been running
