Endlessly running Postgres processes & bad performance after Reinstall/restore

That test serer is on 32GB, 16 core, config is set to 64MB work mem.

EDIT: Shared buffers are at 8GB

Currently doing a vaccuum which looks stuck

Not sure if it’s doing something but it’s been there for 30+ minutes already.

I did put the forum to read only and reboot the VM to end the 7 Postgres processes that were “stuck” there before. Quickly after the restart 2 of these postgres processes were back and didn’t change. Nothing running in sidekiq right now.
