>Synopsis: High CPU load for pagedaemon and mouse freezing
>Category: kernel
>Environment:
System : OpenBSD 7.6
Details : OpenBSD 7.6-current (GENERIC.MP) #477: Thu Dec 12
21:42:00 MST 2024
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Over the last year or two my OpenBSD system has often frozen
(including the mouse pointer) for varying amounts of time,
usually for a second or so when opening a new browser windows,
but sometimes for a few 10s of seconds or even minutes.
When it freezes, top shows high CPU usage for pagedaemon,
sometimes 150%. And systat shows a number of `@` characters in
the Proc display (which i think means something is spinning?),
i've seen this extending halfway across the available bar space.
I upgraded from 7.6 to current a few weeks ago; this does not
seem to have changed the behaviour.
I have 16G of ram, and probably 50 Firefox and tor-browser tabs
open; there doesn't seem to be particularly high CPU load from
these, perhaps because i use uBlock origin and NoScript. `top`
is currently reporting this memory usage:
Memory: Real: 8593M/15G act/tot Free: 769M Cache: 498M
Swap: 7889M/16G
I've tried disabling swap and setting hw.smt=1; neither of these
changed the behviour.
My hardware is a Lenovo x230 laptop.
>How-To-Repeat:
On my system the problem can be reproduced by running firefox
and tor-browser opening multiple tabs in each, and using the
system for a few hours, opening and closing browser tabs,
compiling/linking etc etc.
>Fix:
Unknown
