Thanks Shane ,
Load script used is as follows (basically a curl)
#!/usr/local/bin/escript
main([Filename]) ->
{ok, Data} = file:read_file(Filename),
Lines = tl(re:split(Data, "\r?\n", [{return, binary},trim])),
lists:foreach(fun(L) -> LS = re:split(L, ","), format_and_insert(LS) end,
Lines).
format_and_insert(Line) ->
JSON =
io_lib:format("{\"id\":\"~s\",\"phonenumber\":~s,\"callednumber\":~s,\"starttime\":~s,\"endtime\":~s,\"status\":~s}",
Line),
Command = io_lib:format("curl -X PUT
http://127.0.0.1:8098/riak/CustCalls35m/~s -d '~s' -H 'content-type:
application/json'", [hd(Line),JSON]),
io:format("Inserting: ~s~n", [hd(Line)]),
os:cmd(Command).

The error message is coming from escript and not Riak. It's just a guess but
could it be that the script you're using to load your data into Riak is trying
to load all the data into memory before sending it to Riak?
Can you break your dataset into smaller chunks and load them separately?
Or send the data to Riak as you read it from the dataset without storing it all
in memory?

Using swap in this situation is almost always a bad idea. Your script will end
up running so slowly you will be waiting for days, maybe months, for your data
to load.
