hm. that's very strange... you shouldn't be getting those errors. we haven't had any downtime longer than a few minutes. One thing that does seem to be happening is that moderator actions on 'big items' like banning a user, or removing all their posts seems to completely lock up the lemmy instance. It pegs the CPU at 100% and prevents all backend operations. No clue why. But I haven't heard about this 'no posts' or errors like you are talking about. Can you send us a picture either here or in one of the other communication mediums (discord, matrix, mastodon) when you get an error again?
