comment mysql crash on 512MB Debian server (memory problems?) How to fix?
It makes no difference. A better MySQL (such as MarisDB) squeezed into 512M cannot escape this issue. Your current settings are not tuned to use more memory, so MySQL is as memory friendly as it is going get. You could get Percona Server (which has 30,000 lines of additional code for performance enhancements) and it will be just as choked for memory.

Only those 3 options are immutable for the sake of the fair distribution CPU cycles, Memory, and Overall Performance to all running MySQL RDS instances.
