Re: Periodic lag spike on FreeBSD 13.2-RELEASE (intel graphics / wayland)

Hi Jonathan,

I'm also using Wayland on 13.2, but I believe an older graphics card. I'm not having the same issue.

I do, however, have some weird OOM-like behavior sporadically with Firefox. System will lock up pretty hard for a while, kill something (usually Firefox), and tends to say that the thread timed out waiting for a page. I guess it's probably not the same thing, but thought I'd mention it.

> I get periodic lag spikes. The lag spikes last about 2-3 seconds, almost as if there is some sort of garbage collection running. Wayland/sway continue to function properly, it's just annoying. I do notice these messages in my dmesg and I think they may be related:
