@julian Yeah, I did that: https://github.com/djensen47/nodebb-plugin-dice-bot/blob/master/package.json

@baris I fixed it by installing the latest version from npm.

Side question: why doesn't my dice-bot plugin show up in the "find plugins" tab on Plugins page?

The other problem I'm experiencing is some npm link weirdness with my dice bot plugin.

The main problem at the moment is that it is not installed but enabled and I can't figure out how to uninstall it:

* nodebb-plugin-dice-bot (not installed, enabled)

Also, this seems strange:

2023-10-09T02:05:23.525Z [4567,4568/13500] - error: Error: ENOENT: no such file or directory, open '/var/srv/nodebb/node_modules/nodebb-plugin-require/plugin.json'

I'm seeing this in the logs, I had to disable the plugin to make the error stop:

2023-10-09T01:53:46.325Z [4568/12466] - error: [emoji] Failed to retrieve data for parse ENOENT: no such file or directory, open '/var/srv/nodebb/node_modules/nodebb-plugin-emoji/build/emoji/table.json' {"code":"ENOENT","errno":-2,"path":"/var/srv/nodebb/node_modules/nodebb-plugin-emoji/build/emoji/table.json","stack":"Error: ENOENT: no such file or directory, open '/var/srv/nodebb/node_modules/nodebb-plugin-emoji/build/emoji/table.json'","syscall":"open"}

I also got this deprecation warning during client side styles step, I believe:

Deprecation Warning: Passing percentage units to the global abs() function is deprecated.
In the future, this will emit a CSS abs() function to be resolved by the browser.
To preserve current behavior: math.abs(100%)
To emit a CSS abs() now: abs(#{100%})

I'm upgrading from 2.x to 3.4.3 and I ran into this issue:

So I tried this and it seems to be working now. The only thing I worry about is if I'm using the correct versions of the mongodb libs now.

$ npm update --omit=dev --legacy-peer-deps
$ ./nodebb upgrade

Any thoughts on when the plugin will be fixed for 3.x?

Awesome! Thank you.

I would like to place a widget, specifically an ad, after the first post of a thread.

What’s the best way to handle this? A plug-in? If so, how?

Thanks!

@julian Thanks for the heads up.

@PitaJ said in spawn ENOMEM: Memory leak in 1.19.1?:

Does the memory usage grow quickly at first and then slow down approaching an asymptote?

I believe so.

Today the node processes are at 32% and 30% of memory.
Redis is steady at 2.6% (roughly same as before).

I can keep going but eventually it's just going to keep growing until all the memory is consumed and then it goes to swap and because the memory isn't freeing up, it's not going to help.

It's a slooow leak but it's a leak.

@julian @boris Traffic is normal, probably a bit lower than normal when the incident occurred. Traffic was much higher in March/April 2020 than it is now.

I'll get the memory info but at the moment each process is using 25% of available memory. I rebooted the server about 5 hours ago.

@julian Swap won't solve a memory leak though. In fact, it'll just hide the issue until the server is unmanageably slow, no?

Also, this is new behavior that started sometime between version 1.17 and 1.19 (no issues on 1.16).

I'm replying because we ran into the issue again.

@julian @boris

IIRC, swap is configured by default. I have two processes, 1 per CPU.

MongoDB is on a separate server. Although, it looks like Redis is on the same server. Maybe Redis isn’t cleaning up old sessions, again?

A few users received this error message while trying to login:

spawn ENOMEM

1. Why is login trying to spawn a process?
2. Memory was maxed out when I checked. I'm running with 2GB.

It looks like the memory leak has been here longer:
Jan. 24 is when I upgraded from 1.16 to 1.19

I've never had memory issues with NodeBB

@pitaj Awesome, thank you!

I was running NodeBB 16.x and recently updated to 17.x → 18.x → 19.x and somewhere along the way the API that TripleA (board game software that posts to my forum) uses had a breaking change. Looking through the changelog, I can't figure out which change it was.

For reference here's the issue on TripleA. The stack trace may not be useful here but just in case..
