I'm beginning to doubt that this is particularly associated with system
load (there was speculation that this is related to the scenario of wifi
APs causing NetworkManager and dbus-daemon to go crazy, slowing down the
system, which is a separate bug).
I've used the following script in /etc/init/load.conf to simulate heavy
system load:
description "load"
manual
script
while true; do true; done &
while true; do true; done &
while true; do true; done &
while true; do true; done &
while true; do true; done &
exec cpulimit -l 1 -c 1 -p `ps ax | grep dbus-daemon | head -n 1 | awk '{print
$1;}'`
end script
And it definitely slows things down. But I couldn't reproduce this
specific bug with that running. I actually haven't seen it at all on my
test or daily driver devices since OTA7. I don't know if that means it
is fixed, harder to reproduce, or I've just been lucky.
Ari, you mention seeing this a lot. Are you on OTA7?
