PFPs Have Difficulty Propogating #1821

Closed yaliqmadiq closed 3 years ago

yaliqmadiq commented 3 years ago

Background information

Dendrite version or git SHA: b769d5a25ee1dd298899ab9fec0c31e834f9b99e
Monolith or Polylith?: mono
SQLite3 or Postgres?: postgres
Running in Docker?: no
go version: 1.16.3

Description

Changing profile pictures and clicking save in Element either takes minutes or never at all to sync to other users

Steps to reproduce

Run dendrite for an hour or so
Federation is on
Ask users to update their pfps

This usually resolves by killing and restarting dendrite, then the problem returns.

It isn't clear where the problem is here. How many servers are involved? There's too many variables for this to be a meaningful issue. I would need logs from servers to see if:

The sender server attempted to send the update (or if it was backing off / blacklisted)
The receiving server got the update but couldn't process it for some reason
The receiving server processed it but clients were not notified for some reason

Only 1 server.

Users on bobrtc.tel changing their pfps can't get them to appear to other users also on bobrtc.tel

Seems like a dupe of https://github.com/matrix-org/dendrite/issues/1806 - closing this.
