0.5 GB is ok for letting NIS run. But I guess letting NCC run also and then open a browser that wants to display the page is too much for such a small system. It's just a guess though.
Is this a rented system? You could try to just let NIS run on it, start NCC elsewhere, configure NCC to use your remote NIS and start the browser on the system where NCC is running.
