#Why is on_presence_update causing high memory usage?

Recently, my bot killed itself multiple times as it ran out of memory. My VPS has about 4GB of RAM and my bot was nearly using 70% of it.

After looking into all my active tasks, I found out that sometimes the bot is running thousands of on_presence_update TASKS inside the bot.

Is this code-related or intended when running the function? While going through my code, I didn't encounter a create_task function or else...

I am caching all the server (channels to send a message to and roles to give out) and user settings (whether someone opted-out or not) so I can't really understand this weird behavior lately.

Here's a short snippet:

spotify_settings = await self.get_spotify_settings(after.guild.id)

        spotify_channel = None if not spotify_settings else spotify_settings.get('spotify_channel')
        spotify_channel = before.guild.get_channel(spotify_channel) if spotify_channel else None

        spotify_role = None if not spotify_settings else spotify_settings.get('spotify_role')
        spotify_role = before.guild.get_role(spotify_role) if spotify_role else None
        ###############################################################

        twitch_settings = await self.get_twitch_settings(after.guild.id)

        twitch_channel = None if not twitch_settings else twitch_settings.get('twitch_channel')
        twitch_channel = before.guild.get_channel(twitch_channel) if twitch_channel else None

        twitch_role = None if not twitch_settings else twitch_settings.get('twitch_role')
        twitch_role = before.guild.get_role(twitch_role) if twitch_role else None

What it basically does is checking if the guild is within a defined dict at the beginning and if not, perform one DB query (which is not visible here)

If you have the intents the bot will do presence handling for you

#

It's a known resource consumer and so if you don't need em I'd disable the intents for it

So better not use the Presence intent + displayed event at all? (This would destory the purpose of one of my modules though)

Or if you need it for your bot, then this is simply expected behaviour

#

You can install the extra speedups to help I spose but ram wise yea

#

Go do custom caching or somethin

primal siren
#

could also use cython

#

Well, then I better get rid of it completely if it's that RAM consuming

Thanks for the heads-up
