Wayland error log growing very fast

I use sway with sddm. The log file contains these error messages:
```

Where the "Error: WaylandMessage::Write() too many files to send" is written to it again and again that it has started to consume very large amount of space. At the time I noticed it the log was approx 140GB. The file is here  .local/share/sddm/wayland-session.log

Re: Wayland error log growing very fast

Which compositor command for SDDM are you using? Can you reproduce if you start SDDM with xorg and just start a distinct sway session from there?

If this is actually from the sway session likely some misconfiguration. Are you running some status/notification widget or so in a tight loop rather than with a delay or so?

Re: Wayland error log growing very fast

I don't know. I installed archlinux using archinstall. How do I find out which compositor I am using?

I am running mako as a notification widget. The issue appeared after the new update for sway (1.9).

I configured mako as follows:
default-timeout=5000
max-visible=5
max-history=5

Re: Wayland error log growing very fast

This doesn't have to come from mako, while I haven't found any ref to WaylandMessage::Write()  in either the Wlroots or sway or mako sources, likely sway is running "something" unnecessarily often.

Re: Wayland error log growing very fast

The messages apparently start after running firefox

Re: Wayland error log growing very fast

This definitely seems to be caused by firefox. After I killed it, the log messages stopped. This even happens in Ubuntu 22.04.

But why is the error being triggered?

Re: Wayland error log growing very fast

Having the same problem here on debian with sway. For me all is fine until I put my laptop in suspend and then bring it back from suspend. Afterwards I have to kill firefox and start it again.

This right here is probably related too: https://bugs.launchpad.net/ubuntu/+sour … ug/2051838

I could be very wrong but I have the feeling this started happening when I upgraded to firefox 123 on February 23rd.

Re: Wayland error log growing very fast

Can confirm that when starting firefox with

MOZ_ENABLE_WAYLAND=0 firefox

I don't have the problem.
