Sync warning: Unable to send updates to client

Hello. We are receiving this warning every second in the logs and was curious if there is a way to stop it. It doesn’t seem to be affecting anything but makes it difficult to read incoming messages. We are running 8.1.12


Bumping this - I am having the same issue I have pages of this warning -

Based on the error it looks like the server is trying to send updates to a client that is no longer connected. Restarting the gateway fixes the issue but that’s not an option the customer right now. More of an annoyance than a functional problem but it does make watching the logs difficult without filtering.


Until a more permanent fix is available, you can always just turn off that logger.

Experiencing the same issue!

I did turn off the ‘sync’ (perspective.ClientSession.Sync) logger as suggested by pturmel which is helpful but I don’t want to restart the gateway at this time.

Just wanted to share, because this seems like a bug that should be looked into. Maybe after awhile the gateway should recognize the client isn’t available.

Same issue, Ignition 8.1.17, July 2022.
Is there a known way to clear this issue without restarting the gateway?

Managed to block the log spam by setting the “perspective.ClientSession.Sync” logger to “OFF”.

To add my voice to the chorus, same issue, Ignition 8.1.14, October 2022. Same temporary fix as above. Any news on a more permanent solution, and one that ideally doesn't involve restarting the gateway?

I tried this one. But this type of "sync" log is continuously logged in gateway. FYI, I attached the logs snap

Any resolution to this?

I am running 8.1.22 and just saw this for the first time after having upgraded to 8.1.22 about a month ago.

Same issue, would be great if Inductive Automation could give a resolution for this one! Using 8.1.20

I did notice that hovering over the magnifying lens shows this message which points to an issue with a particular Perspective screen. Each line is about a different screen though!! No idea what that "@C$0:65" in the end means!?!?
