Well, here's what the man page for SSL_get_error has to say
about SSL_ERROR_SYSCALL:

  Some I/O error occurred.  The OpenSSL error queue may contain
  more information on the error.  If the error queue is empty
  (i.e. ERR_get_error() returns 0), ret can be used to find out
  more about the error: If ret == 0, an EOF was observed that
  violates the protocol.  If ret == -1, the underlying BIO
  reported an I/O error (for socket I/O on Unix systems, consult
  errno for details).

So, can you please check what the value of rc is when the
problem occurs. It may be that the connection is being closed by
the peer when the SSL engine is not expecting it (or possibly a
bug in openssl_operation that means it erroneously reports EOF
to the SSL engine).

Cheers,
Chris
