concurrent requests

[Norman Barker]

Hi,

I have set up a JMeter test script against couchdb and in particular
the multiview I have set up, when 1 or more requests are concurrent I
get

[error] [<0.2406.0>] Uncaught error in HTTP request: {exit,
                                 {{badarg,
                                   [{erlang,byte_size,
                                     [{'$gen_call',

I know this is a general questsion, but what does this mean in OTP?

thanks,

Norman
