Just a guess: looks like SSL is waiting for /dev/random (blocking random) to answer, and /dev/random can take a long time to answer if there's not enough entropy in the system.
Usually you can choose betwenn /dev/random and /dev/urandom (non blocking but cryptographic quality depending on entropy) by configuration. I didn't follow this thread, so I don't know, if we are talking about OpenSSL or Java SSL. I hope others will comment to complete the solution.
