I don't have older metrics on Marvel. I turned it on few days ago to see if it could help with solving the problem
I couldn't find Field data memory in node statistics. Where can I find it?

What does the field data memory looks like?

May be you could look in the past before things starting to be worse.

This is what Marvel shows for old GC in the last 6 hours for that node:

It sounds like the old GC is not able to clean old gen space enough.
I guess that if you look at your Marvel dashboards, you can see that on old GC.
So memory pressure is the first guess. You may have too many old GC cycles.

Thanks for the answer David
I added this setting to elasticsearch.yml some days ago to see if that what's the problem:
discovery.zen.ping.timeout: 5s
discovery.zen.fd.ping_interval: 5s
discovery.zen.fd.ping_timeout: 60s
discovery.zen.fd.ping_retries: 3
If I'm not mistaken, with those settings the node should be marked as unavailable after 3m and most of the times it happens quicker. Am I wrong?
On Thu, May 29, 2014 at 10:29 AM, David Pilato david@pilato.fr wrote:
GC took too much time so your node become unresponsive I think.
If you set 30 Gb RAM, you should increase the time out ping setting before a node is marked as unresponsive.
And if you are under memory pressure, you could try to check your requests and see if you can have some optimization or start new nodes...
My 2 cents.

I've been analyzing the problem with Marvel and nagios and I managed to get 2 more details:
- The node restarting/reinitializing it's always the same. Node 3
- It always happens quickly after getting the cluster in green state. Between some seconds and 2-3 minutes
I have debug mode on in logging.yml:
logger:
log action execution errors for easier debugging
action: DEBUG
But i dont see anything in the log. For instance, this is the last time it happened at around 9:47 the cluster became green and 9:50 the node restarted

Hi,
I may be wrong but it seems to me you have a problem with your network. It may be a flaky connection, broken nic or something wrong with your configuration for discovery and/or data transport ?

Hello
We have a cluster of 3 nodes running Ubuntu 12.04.4 LTS 64bits, and elasticsearch v1.1.1
It's be running flawlessly but since the last weak some of the nodes restarts randomly and cluster gets to red state, then yellow, then green and it happens again in a loop (sometimes it even doesnt get green state)
I've tried to look at the logs but i can't find and obvious reason of what can be going on
I've found entries like these, but I don't know if they are in some way related to the crash:

For instance right now it was in yellow state, really close to get to the green state and suddenly node 3 autorestarted and now cluster is red with 2000 shard initializing. The log in that node shows this:

Any Idea what can be going on or how can I trace what's happening?
