Problem description:
Hi, my Traefik is using a lot of RAM and occasionally restarts and users get error:
❗ Some of your messages were not sent

Additional context

I noticed the similar kind of RAM usage spike when I select a bunch of inactive users (~ 500) on Synapse Admin created by bridges to delete them all at once. Restarting Traefik did reset the RAM usage, so it was temporarily issue as it repetitively occurred.

Thanks for answer. I’m seeing this issue several times a day: Traefik gradually consumes more RAM over time until it hits a limit and restarts. And I’m not doing anything in the admin panel.

Hmm, I've been having a lot of disconnections recently and think this may be related. Will try adding Synapse Admin and deleting the bridged users to see if that addresses it.

edit: wow, I had over 3000 deactivated bridge users. Lots are from a private IRC server so unsure how they got in there...
