Hi Sunil, I am not having two threads working on the same SSL connection at the same time. I have one thread which does the handshake (SSL_accept) and AFTER the SSL_accept is finished successfully, I transfer the ownership of the connection (ssl and fd) to the second thread. The second thread does the read,write and close of the connection thereafer.
