Outgoing presence exploded in 1.35.0rc1

See original GitHub issue

Description

There seems to be a huge spike in outgoing presence right after 1.35.0rc1 was released. Incoming presence also went up, but not as much.

My federation sender is also having trouble with metrics after the 1.36.0rc1 upgrade (which is what I was looking into when I noticed the presence problem), but that might be a separate issue:

I can also confirm that applying the patch significantly reduces outgoing transactions and the CPU usage of our federation sender: grafik grafik

Will this be in the next rc or in 1.37rc1? If it is the latter, I’ll just add the patch to my patchset, otherwise I would wait until rc2.

The branch release-v1.36 was created last Tuesday, so under normal circumstances this wouldn’t make it into a release candidate until 1.37.0rc1 on June 22nd. However, the patch applies cleanly to the release branch, and it seems like a big enough deal that we should consider backporting to 1.36 and issuing an rc2. Let me think on that.
