Concurrency problem with ActiveRecord

[Serg Fedosov]

Hi!
I have some error with AR 4.x.

I get code from examples/activerecord folder and little change this https://gist.github.com/Wolfer/10720433.
When I run a simple benchmark (ab -n 200 -c 20 -T application/json -p /tmp/post_data "http://localhost:9000/"), I get the following error: https://gist.github.com/Wolfer/10720744
What am I doing wrong?

Thank you.
P.S. sorry for my bad english

    body = env['rack.input'].read
    MessageLog.create request: body

    the body is raw post , like "name=xx&city=bj",  you can't use it directly

In my case need write raw input to database.
In any case, it is not important for subject error. Code like

# env['rack.input'].rewind

# body = env['rack.input'].read

MessageLog.create request: 'anything string'

generates the same error
