My server handles incomming SSL connection. If all connections are handled within one threads evertyhing works fine. In multithread configurations (pool of threads handle connections) SSL_read() fails very often when using openssl-1.0.0-beta5 with SSL_MODE_RELEASE_BUFFERS flag set.
When flag SSL_MODE_RELEASE_BUFFERS is _not_ set then multithread version works fine. I think it may be some race condition in SSL_MODE_RELEASE_BUFFERS implementation inside openssl.
