Hi Prabhu.
For each client the SSL_CTX object is unique. And when the application starts, callback functions are set for multi threaded support. And when the app tries to do SSL_connects in non persistent connections[ a new TCP for each SSL session], all sessions are successful even under high stress. I have not come across concurreny issues yet.
By callback functions do you mean CRYPTO_set_locking_callback() and CRYPTO_set_id_callback()?
