Rocket.Chat 6.3.0 high cpu usage

[kk_cloudron]

Hello,

for some time now my Rocket.Chat instance (6.3.0 - package version: chat.rocket.cloudronapp@2.39.0) has been causing high CPU usage.
Does anyone else observe the same situation?

Regards, Kai

(the low point is a Rocket.Chat app restart)

If you open a Web terminal and do htop , do you see it using 100% cpu?

https://github.com/RocketChat/Rocket.Chat/issues/30016 is the closest I found but for previous version.

Yes, i saw some posts to older versions too but thought none fits to my situation.. also tried some setting-changes - but none of them was the solution..

I restarted the app again and the log looks quite well - there occures just one error from time to time while startup:
"=> Healtheck error: Error: connect ECONNREFUSED 172.18.16.54:3000"

But im not sure if it has any affect on the cpu usage in my case, cause htop shows that a js-file causes the cpu usage (between 70 and 115) and not the db server

This part is fine. It's the healthcheck route failing (when the app is still coming up).

Also, a 6.3.1 is released now, maybe things are better with the new release. We are waiting for the release tarball to appear to publish the new package.

Update: Rocket.Chat updated to package version 2.39.1 (v. 6.3.1) but the cpu usage is still high.. I'll have to keep looking.

Hi again,
just did an update again

... and watched the cpu load. First it was nice but after a while (maybe 15 minutes) the load rises again (10:43)

But the last log messages of Rocket-Chat were from 10:35...

Do you know if there is any way to find out, which process of Rocket.Chat rises the cpu load?

@kk_cloudron Maybe you can open a bug upstream. It's hard for us to know why it's using high CPU. There's a bunch of existing issues upstream . Some issues point to specific features like OTR, it seems the high cpu usage is known:

• https://github.com/RocketChat/Rocket.Chat/issues/29515
• https://github.com/RocketChat/Rocket.Chat/issues/25001
• https://github.com/RocketChat/Rocket.Chat/issues/13461
• https://github.com/RocketChat/Rocket.Chat/issues/25968

Unfortunately, most of the issues are still open and not conclusive.
