Re: Riak shuts down itself after couple of minutes

[Alex Moore]

Hi Hao,

Looks like you might be running into an EMFILE error:

What’s the open files limit on your nodes?

Thanks,
Alex

Hi Hao --

As Alex said, the error you're receiving is generally related to open file
limits set by your OS configuration. Riak requires a large number of
available open files handles. You can find information on how to up your
limits here: http://docs.basho.com/riak/latest/ops/tuning/open-files-limit/

Hope that helps!

Thanks!

Cuyler
