The size of this log file increases over time. If you reboot/restart your desktop daily, the file will be overwritten and remain at a reasonable size - my wayland-session.log is currently ~ 165kB. Dale does not reboot often, so the file will grow until it is deleted/rotated. > > I added the commas to the file size.

You can automate the rotation of this file with logrotate. Just add it in the logrotate.d/ directory and specify a maximum size you're happy with, e.g. "size 3M" and/or how long before it is rotated, e.g. "weekly".
