Hi All,

This is a bit off topic, but we only see this on some of our elastic search 
hosts, and it is also the only place where we enable mlockall for java which is 
our understanding is a strongly recommended best practice.

Basically we from time to time see kswapd run away at 100% on a single core.

It seems to hit our master nodes more frequently, and they also have the least 
amount of memory.
masters are:
CentOS 6.4
4GB RAM
4GB swap
ES_HEAP_SIZE=2908m



Does anybody know much about this and how to prevent it?
We have hunted google groups, but have not really found the magic bullet.

We have considered turning off swap and seeing what happens in the lab but 
prefer not to do that unless it is well known as the correct solution.

Thanks,
- Mike
