The individual threads themselves send complete messages with each write. This should present no real problem from a synchronization perspective.

Have you enabled OpenSSL locking? OpenSSL uses a myriad of global
variables and you have to initalize a set of mutexes and set lock/unlock
callbacks via ssl. See

example.
