wayland-session.log

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:123.0) Gecko/20100101
Firefox/123.0

Steps to reproduce:

1. Lauch Firefox
2. CPU usage rises to 80-90%
3. The ~/.local/share/sddm/wayland-session.log grows in size very fastly, consuming large amounts of disk space.
4. The log file is spammed with the message "Error: WaylandMessage::Write() too many files to send
: "

Actual results:

This only happens whenever I start firefox on sway (wayland), regardless of whether I reload  swaywm using mod+shift+c. CPU usage stays at 80-90% and the log file starts to consume disk space. At the time I noticed it, the log file was ~140GB with all of the lines being "Error: WaylandMessage::Write() too many files to send
: "

Expected results:

CPU usage should be normal.
Log files shouldn't consume large amount of space in a very short period of time.

That's interesting, Thanks. Do you see that on Sway only? Can you test Mutter for instance?

It looks like Sway sends too many files over IPC so we can't handle it.
As a workaround you can run Firefox with MOZ_DISABLE_WAYLAND_PROXY=1 env variable set.

It's because we write max MAX_LIBWAY_FDS-1 fds.
