Can I get a list of all currently-registered atoms?

Question

My project has blown through the max 1M atoms, we\'ve cranked up the limit, but I need to apply some sanity to the code that people are submitting with regard to list_to_ato

Answer 1

I'm not sure if there's a way to do it on a live system, but if you can run it in a test environment you should be able to get a list via crash dump. The atom table is near the end of the crash dump format. You can create a crash dump via erlang:halt/1, but that will bring down the whole runtime system.
