1.  Don't call SSL_shutdown(), rather just call SSL_free() and close the
    socket using close(), IIRC SSL_set_fd() (you should not need to use
    BIO_set_fd) leaves you as the owner of the socket to close or not.

2.  DO NOT reuse the same SSL handle for multiple connections, create a
    new one for subsequent connections, but you can and generally should
    reuse the SSL_CTX.
