What is the erlang version?

[Yamilquery]

I had the same Issue in our AWS micro instance.

I'm using:

Erlang/OTP 21 [erts-10.0] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1]

When I use kiex on my local environment, I can run without any kind of trouble.

In my local machine I have:

Erlang/OTP 21 [erts-10.0.4] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] [dtrace]
