OpenSSL is thread safe, or at least has been in the past, I've tested an FTP application sending hundreds of SSL sessions each using a separate thread. But OpenSSL has changed a lot in the last two years, there is a ICS unit OverbyteIcsSslThrdLock which used to provide OpenSSL with thread locking for 1.0.2 and earlier, but is no longer used for 1.1.0 and later since OpenSSL does locking internally. I've not tested heavy thread use for a while, since it is rarely necessary with ICS, it just complicates applications and introduces problems. Which OpenSSL and ICS versions are you using?
