2 weeks and probably about 15,000,000 records in a ML Job giving me the following error-
[2017-03-24T11:38:07,458][WARN][o.e.m.j.JvmGcMonitorService] [es154.162.client2] [gc][816] overhead, spent [925ms] collecting in the last [1s]

shutsdown elasticsearch etc. I'm still figuring out x-pack etc so there's probably something I'm doing. It's a really beefy server.
There's a couple other questions like this but no answers.

Everything I'm reading says this is a memory error but it looks ok..
root@elkstack:/var/log/elasticsearch# free -mh
total used free shared buff/cache available
Mem: 251G 4.8G 133G 2.6G 113G 242G
Swap: 5.3G 0B 5.3G

Hi,
You can configure the amount of memory the JVM uses by editing the jvm.options file in the Elasticsearch config directory. Take a look at the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html) for more details.
The default out of the box setting it 1G, you have a big machine so a much larger value is fine but don't give the JVM more than 26Gb of memory as it can no longer use compressed oops. `-Xms26g` and `-Xmx26g` are the max values you should use.
