What you send does not seem to indicate any errors other than the "erlang has 
closed" message.  Isn't there something else you can share with us?  a crash 
log or something?

Hi guys,

I'm having a problem with the Erlang VM going down for a Riak node that 
receives a MapReduce request.

My setup is this:

I run three Riak 1.2.0 nodes, each on an Ubuntu Server 12.04 guest OS on 
VirtualBox 4.1.20. The host OS is Windows. I send requests through our own Riak 
client library, (uGameDB for the Unity game engine), which uses the PB 
interface. When my test script sends a MapReduce request to one of the nodes, 
the node fails instantly.

The error.log and crash.log files are empty. The erlang.log.1 file says: 
http://pastebin.com/1LHqYCaB

I have tested this with different versions of our client library, specifically 
with versions that have previously been confirmed to work, to rule out any 
error on the client side. I have also tried with different numbers of nodes, 
and it is only the node that receives the MapReduce request that fails.

Any help is greatly appreciated!

Kindly,
