If for example you send 1K from client, data is encapsulated in SSL stuff and send to server (if you send for example ~32kb client may send two SSL records because max data size is ~16kb). When client receives this record 1kb data will be but in buffer, and if you will read 500b from SSL layer, second 500b will stay in buffer and waiting in select() will not gave this data. There is function SSL_pending() for checking data in SSL buffer and if this function give you hit that there are data in SSL buffers you should just call SSL_read().
