IOException running akka-sample-hello via JMETER

[hitoshi g]

Hi everyone,

We're experimenting Akka's Microkernel with Mist, and so far it has
been a blast!

One issue: as the subject mentions, we're getting bunch of
EofExceptions when we're running the sample app 'akka-sample-hello'
via JMeter (100 threads, 100 loops, total 10000 requests).

Source code and conf files are pretty much the same as the ones
provided.

Version is 1.1.2

Any help is greatly appreciated.

Thanks,
Hitoshi
