I am using the OpenSSL that was compiled for my version of
Mixmaster as I am running a middle remailer on the same VPS. It is
OpenSSL: 1.0.1e
Does Tor log a message when it starts recommending an optimised version of OpenSSL?

512KB
This is likely to be your issue. 512 MB is not enough for a large relay.
Tor will limit its memory and connections to stay under about 3/4 of the memory you have.
Try 1GB.
