> Once I upgraded to 0.11.0, I'm getting the following error occasionally:
> THRIFT LOGGER: TConnection::workSocket(): THRIFT_EAGAIN (unavailable resources)
> I tracked this to the following change: [https://github.com/apache/thrift/commit/808d143245f4f5c30600fab31cf9db854cbf5b48#diff-fe8fec8ec38ea35df64cfcc305e3ab08]

> {code:java}
> // Work the socket right away
> - // workSocket();
> + workSocket();
> {code}
> While adding SSL support, @dthaluru has re-activated the above line. From my own testing, this causes occasional THRIFT_EAGAIN exceptions. It seems like this is due to calling workSocket() too early and the socket gets a read call in non-blocking mode before it has data.
