Update: these seem to be mostly resolved. The option mentioned below doesn't seem to be useful.
I've updated the source with a new option. You can now run with the
-useevp=0
This will switch off the EVP library, which may be the source of a memory leak.
The EVP library is what allows the AES-NI instructions, so performance will be slower. You won't want to use this if you're mining, but for a node or a block explorer, this should cut out the memory-leak crashes.
Let me know how it works out.
