Lemmy starts out pretty chill, but the longer it is running, the more CPU it’s using. Until I restart it again, and then the process starts over again. It’s just /app/lemmy that’s eating the cpu cycles. Looks like there are some threads that keep requeueing themselves, until eventually that’s all it’s doing.
Does anybody have any clues or pointers about this?
I’m running 0.17.4, haven’t made the jump yet to 0.18.
You must log in or register to comment.
I’ve been running the 0.18 docker build since it was released. Just took a look and it’s CPU usage has remained <3% on load since the release. Admittedly my instance has only a handful of users, but it might be worth upgrading to 0.18?
Yeah, my instance doesn’t have a lot of users, but it does have a lot of posts (few thousand per day). It might be all the updates it’s sending out.
I guess I’ll just have to give 0.18 a try then.
I’d give it a try. I read there were federation issues between 0.18 instances and those <0.18. Might be linked to that.
I restart my lemmy container once an hour.I saw the lemmy.world admin say that’s what he was doing back whenever the new sort algos came out. I still have mine doing that. @ruud@lemmy.world
Can’t say I see this issue on 0.18.
I can only speak to my instance but I’m not seeing anywhere near that amount of utilization. I am on 0.18.1.
I switched to 18.1 this weekend, and the cpu is basically bored now ;)
That’s good :D
What is your server doing?
Lots of local users logging in and reading content? Federation outbound sending of new content from your server to other servers? Federation inbound?
Sorry, I cannot find the comment now , one of the Android app developers responded to a ‘my phone is getting hot’ comment that caching was the problem. Perhaps this is related?
I think that’s more of a client issue than a server issue though.
