R2-45

R2-45 monitors overall volatile memory usage and when memory usage goes to or beyond what it considers too far (meaning that the poor system switches to super-slow swap memory) it kills progressively a list of programs it has in its internal blocklist. As it does this it notifies you of its actions and, when it has done all it can based on its blocklist, it sends a final message of warning. It is not perfect, but it is trying. And really, the pursuit of a positive contribution to reality is really all for which anyone or script can hope.

setup

pip install r245

usage

Just run it.

r245

You can ask it for help if you want to learn how to specify via command line options and arguments the critical RAM usage limit or a custom blocklist.

r245 --help

example program to demonstrate large memory usage

x = bytearray(512000000)
