Synapse v1.142.0 logging context warnings

[Nemric]

Hi :)
I can see a lot of logs like that :

2025-11-11 11:44:15,898 - synapse.logging.context - 105 - WARNING -  - run_in_background(UcxFX): deferred already completed but the function did not maintain the calling logcontext call_later (found sentinel)
2025-11-11 11:44:15,899 - synapse.logging.context - 105 - WARNING -  - Expected logging context call_later was lost

2025-11-11 11:46:55,988 - synapse.logging.context - 105 - WARNING -  - Expected logging context call_later was lost

I did see that there is some work done on this subject in #19090 and #19108

Synapse v1.142.0

[MadLittleMods]

In #19090 (shipped in Synapse v1.142.0), we added a warning to detect when our assumptions are being broken. So this kind of thing was happening before Synapse v1.142.0, it just wasn't being called out. To give some peace of mind, the warnings are harmless in terms of the app working (only logs/tracing won't be totally correct).

I would need more surrounding context in the logs to determine what's causing this (provide more logs).

Any obvious way to reproduce and trigger this?

Hi, thanks for answering ^^
I'm running synapse in a K8s cluster as a deployment, so, from the OCI image : docker.io/matrixdotorg/synapse:v1.142.0
I don't really have more logs than pages of :

2025-11-12 20:26:05,895 - synapse.logging.context - 105 - WARNING -  - run_in_background(PopxM): deferred already completed but the function did not maintain the calling logcontext call_later (found sentinel)
2025-11-12 20:26:05,896 - synapse.logging.context - 105 - WARNING -  - Expected logging context call_later was lost
2025-11-12 20:26:20,661 - synapse.logging.context - 105 - WARNING -  - run_in_background(IWged): deferred already completed but the function did not maintain the calling logcontext call_later (found sentinel)
2025-11-12 20:26:20,662 - synapse.logging.context - 105 - WARNING -  - Expected logging context call_later was lost
2025-11-12 20:26:25,437 - synapse.logging.context - 105 - WARNING -  - run_in_background(BIBVQ): deferred already completed but the function did not maintain the calling logcontext call_later (found sentinel)

that said, Synapse seems to work well ...

[edit remove useless lines]

@Nemric Can you try enabling logging for synapse.logging.context.debug for a second while this happens? It will be very noisy, so you can disable it again as soon as you copy-paste some logs:

loggers:
    synapse.storage.SQL:
        # beware: increasing this to DEBUG will make synapse log sensitive
        # information such as access tokens.
        level: INFO

    synapse.logging.context.debug:
        level: DEBUG

It may or may not capture something obvious. What we really want to see is what's calling clock.call_later(...) which I've created a PR to add the necessary debug logs for (#19173). If you know how to run Synapse from a branch, you could also try that out but I'm guessing that may be tricky if you're using Kubernetes.

Hi, I did run synapse with DEBUG logging level, I then get some WARNING and select from logs what happen between 2 of them :

Looking at your new logs

Thanks for the new set of logs! It looks related to the federation_transaction_transmission_loop and some call_later call that we should identify.

Logging for synapse.util.clock

#19173 is now merged which means we can also get logs specifically where we need them.

Here is the Docker image from develop that includes the change:

• ghcr.io/element-hq/synapse:sha-5d545d1
• docker.io/matrixdotorg/synapse:sha-5d545d1

Updated logging config:

loggers:
    synapse.storage.SQL:
        # beware: increasing this to DEBUG will make synapse log sensitive
        # information such as access tokens.
        level: INFO

    # So we can see how the logcontext is changing
    synapse.logging.context.debug:
        level: DEBUG

    # So we can debug which `clock.call_later(...)` we're interacting with
    synapse.util.clock:
        level: DEBUG

root:
    # Good to generally see what's happening on the homeserver
    level: INFO

    # handlers: ....

Fixing lost logcontext with deferred

I've also fixed up various places where we may be mishandling logcontext with Deferred:

• Fix bad deferred logcontext handling #19180
• Fix potential lost logcontext when PerDestinationQueue.shutdown(...) #19178

These aren't merged yet but just giving a bigger picture of things happening. I don't know if this actually solves the specific problem you're running into but should eliminate one side of things.

Hopefully a new set of logs can help us pinpoint things.
