Port server memcached exit with status 137


Hi guys!

We have a problem with my Couchbase claster (2.5.1) on Linux server

When we start to fill bucket with data one of node is failed with such error: “Port server memcached exit with status 137”

I’ve googled this error and found some discussion there guys said that problem could be in OOM Killer.

So, how can I fix this problem.
How can I guaranty that OOM Killer won’t kill my couchbase process?

In documentation I didn’t find any recommendations of how much of total memory I can use for Couchbase.
Is there any formula?
