Lots of Operation Timed Out messages (lemmy.notmy.cloud)

I just started to self host my instance this week. Is it normal to get a lot of these error messages? My instance seems to be working from an end users POV.

Hi. This is typical right now of lemmy fderation based on my own personal testing.

There is a 10 second timeout in HTTP that I think is on the short side.
The peer servers your lemmy instance is trying to reach are suffering from big PostgreSQL overload due to some TRIGGER logic in lemmy 0.18.2 and earlier. Hopefully the 0.18.3 release will be fixed up and deployed on many of these sites fixing the worst of it.

As you also can see, one single http timeout spits out tons of log lines. I created a GitHub issue to try and get that down to one line so my server isn't constantly writing to logs. https://github.com/LemmyNet/lemmy/issues/3627
