Very higher server load


I have a Rocketchat server, installed as a Snap on Ubuntu, that is struggling under load. The machine frequently reaches a load average of 20 or even 30, and at those times node frequently takes up 300% of CPU or more, while using up all its 16Gb of RAM. I’m not noticing any particular errors in the log.

How might I alleviate this? Hardware upgrade? OS tuning? Some kind of proxy? (I tried to use Cloudflare, but it caused new problems.) As a workaround, I’m just restarting the server whenever it gets like this, and that helps for a little while. Happy to pay for someone’s time to fix the problem if that’s required.

did you solve this problem?

No, not yet. My workaround is just restarting at regular intervals. But it seems like this may be worth trying.
