The Slack app on my mac kept using up a lot of RAM frequently. I'd have it running for a few days and suddenly the laptop would be unusable, with only ~200MB of RAM free. Slack would suddenly be using 2-3GB of memory. Kill slack and everything works fine.
I've restored to using slack on Safari now. This problem still occurs, but reloading the slack tab is easier then finding and killing the slack process.
