> {{IsConnReset()}} aims to check if the given exception is due to a stale
> connection. Apparently, it's missing the case in which the error code is
> ECONNRESET.

> bool IsConnResetTException(const TTransportException& e) {
> // Strings taken from TTransport::readAll(). This happens iff
> TSocket::read() returns 0.
> // As readAll() is reading non-zero length payload, this can only mean
> recv() called
> // by read() returns 0. According to man page of recv(), this implies a
> stream socket
> // peer has performed an orderly shutdown.
