basho_bench crash using PB client

[Peter Herndon]

Hi all,

I'm running into a crash every time I try to run a benchmark using the
PB client.  The HTTP raw client works just fine. Can someone give me
an idea what the source of the problem might be?  I'm a bit stumped as
to where to look.

Thanks very much!

 Here's the error output from basho_bench:

=ERROR REPORT==== 9-Aug-2010::16:26:03 ===

                     {riakc_pb,encode,1},
                     {riakc_pb_socket,send_request,4},

                     {proc_lib,init_p_do_apply,3}]}


And here's my config:


{mode, max}.

{duration, 10}.

{concurrent, 1}.

{driver, basho_bench_driver_riakc_pb}.

{code_paths, ["deps/stats",
              "deps/riakc",
              "deps/protobuffs"]}.

{key_generator, {uniform_int, 35000}}.

{value_generator, {fixed_bin, 3}}.

{riakc_pb_ips, [{127,0,0,1}]}.

{riakc_pb_replies, 1}.

{operations, [{get, 1}, {update, 1}]}.


And here's the crash report from log.sasl.txt:
