As others said, Synapse can sometimes be very resource-hungry. It might be worth giving a try to Conduit and Dendrite, which are alternative Matrix server implementations and especially Conduit seems to be focused to by lightweight. Although I do not have any personal experience with them and it seems that they are most likely a lot less mature than Synapse at the moment.
It would be helpful if you could provide more information. Which setup? OS? Dockerinstall or bare metal? Did you follow a specific Guide? Link it please if you followed one.
With this you will get better answers 🌞
Ubuntu 22.04, bare metal. I followed this guide and the official docs as well as tweaked it for my needs. I posted my yaml in another comment as well
That's very normal regarding the crash trying to join #matrix:matrix.org. You need much higher specs and need to be using Postgres database, MySQL probably won't handle it.
Can you post a sanitized version of your homeserver.yaml so we can take a look at your config?
Also are you running docker or something else?
Heres my yaml. I quickly skimmed the docs and set it up last night so its probably pretty jank. So I guess my large channels issue is solved and I need better hardware. As for the the Error 500 I get while uploading profile pictures, this is the exact error I get:
Failed to save your profile MatrixError: [500] Internal server error (https://matrix.*.xyz/_matrix/media/r0/upload?filename=5db2-6c61-48eb-827c-f09ec246af71.png)
Your config looks good to me. I'm thinking you may have a permissions error with your media store folder. What permissions do you have set for it?
