Can you please add to the Jira how you reproduce the error. It would be great 
to have this replicated in either a Tsung or Jmeter test plan based on the 
recipe. We can then run this before releasing each tag.

Hi Branden,

Thanks for looking into this. One of our systems guys has found a method to 
reproduce this problem. Stack trace and server logs have been sent to you.

Regards,
Mark.

Hi Mark, thanks for the stack trace. Unfortunately, nothing jumps out
at me. Can I get a wider set of app server log files to track down
other exceptions? If it's feasible to zip them all up for me, that
would be great.

Thanks,
Branden
