Description

With the version 1.92.2 which also contains the Debian update, I suspect that some python libs has changed.
It seems to affect the logging.
Config wise I use the logging sample config you can find here.

Steps to reproduce

Steps to reproduce:

  • pull synapse version v1.92.2 or (currently) latest via Docker
  • recreate and start
  • Exception appears, synapse doesn't run

Steps to unreproduce:

  • pull synapse version v1.92.1 via Docker
  • recreate and start
  • synapse runs

Homeserver

chaospott.de:8448

Synapse Version

v1.92.2

Installation Method

Docker (matrixdotorg/synapse)

Database

postgres15, single, no ports or restored backups

Workers

Single process

Platform

VM, firewalled Debian 10

Configuration

No response

Anything else that would be useful to know?

Trying to reproduce this locally, I see something different:

$ docker run --mount type=volume,src=synapse-data,dst=/data     -p 8008:8008     matrixdotorg/synapse:v1.92.2
Starting synapse with args -m synapse.app.homeserver --config-path /data/homeserver.yaml
This server is configured to use 'matrix.org' as its trusted key server via the
'trusted_key_servers' config option. 'matrix.org' is a good choice for a key
server since it is long-lived, stable and trusted. However, some admins may
wish to use another server for this purpose.

To suppress this warning and continue using 'matrix.org', admins should set
'suppress_key_server_warning' to 'true' in homeserver.yaml.

RuntimeError: can't start new thread

It looks like you'll need to upgrade your host's installed version of docker (or podman or similar). See https://stackoverflow.com/a/70093119/5252017 or https://medium.com/nttlabs/ubuntu-21-10-and-fedora-35-do-not-work-on-docker-20-10-9-1cd439d9921.

Can you try that out and see if that resolves the problem for you?

I get these logs, running Docker 20.10.24+dfsg1

Container should be the newest one, here is my docker-compose.yaml section for synapse:

services:
  synapse:
    image: docker.io/matrixdotorg/synapse:latest
    # Since synapse does not retry to connect to the database, restart upon
    # failure
    restart: always
    # See the readme for a full documentation of the environment settings
    # NOTE: You must edit homeserver.yaml to use postgres, it defaults to sqlite
    environment:
      - SYNAPSE_CONFIG_PATH=/data/homeserver.yaml
    volumes:
      # You may either store all the files in a local folder
      - ./synapse:/data
      # .. or you may split this between different storage points
      # - ./files:/data
      # - /path/to/ssd:/data/uploads
      # - /path/to/large_hdd:/data/media
    ports:

I had been running synapse using this guide previously, as a different user, but I want to switch to Docker.
