> Project: Traffic Server
> Issue Type: Bug
> Components: SSL
> Affects Versions: 5.2.0, 5.3.0
> Reporter: Susan Hinrichs

> Reported by [~esproul] and postwait.
> The return value of SSLNetVConnection::read_raw_data() is being ignored. So
> EOF and errors are not terminated, but rather spin until the inactivity
> timeout is reached. EAGAIN is not being descheduled until more data is
> available.
> This results in higher CPU utilization and hitting the SSL_error() function
> much more than it needs to be hit.
