connection error bit set to 1

[Ortal]

Hello,
I am writing a nginx module.
I would like to know it which flow is the error filed of the connection set
to 1, I am running a test which the nginx epoll call
ngx_http_finalize_request  with: r->connection->error = 1, this will
terminate my request before I finished with my job.

Thanks
