Title: [SOLVED] High systemload after update - libmm-glib
Post by: katinka on 12 September 2021, 11:42:07
Hi there,

after updating today I got abnormal systemload. CPU load was about 40-45% and CPU always run on maximal frequence. Temperature gone up to 90° degrees. Systemmonitor lokked normal, no process consumed high ressources.

The problem was gone after downgrading libmm-glib.


Installed newest (not the weekly) KDE-ISO with runit 3 days ago on Intel notebook.

Regards

Hi @Artist

top...why didn't I think of it myself and only used the system monitor... ::)

First Screenshot is with libmm-glib-1.16.10-1 and second with updated libmm-glib-1.18.0-1

I just pushed a new update for ModemManager, I noticed it was flooding console with plugin dir not found, which may be why there is a higher cpu load. For me the error has stopped and my cpu load is at 4,0 or so but I didn't look before the update and see if it lowered. I hope this update will fix your load issue.

Hello all,

I noticed abnormally high CPU usage after restart following yesterday's upgrade.

I suspect it's the new version of modemmanager that causes it  (1.16.10-1 -> 1.18.0-1).

The processes that loaded the CPU were dbus-daemon and nm-applet.

It also keeps flooding logs with thousand repeated messages like this:

dbus-daemon[1129]: [system] Rejected send message, 1 matched rules;
type="method_call", sender=":1.126" (uid=1000 pid=2128 comm="nm-applet
") interface="org.freedesktop.DBus.ObjectManager"
member="GetManagedObjects" error name="(unset)" requested_reply="0"
destination=":1.14390" (uid=0 pid=30018 comm="/usr/bin/ModemManager "

In console / another tty that is seen before reboot / poweroff there are numerous modemmanager-related messages as well.

Filed a report upstream to see about fixing this. I got rid of the console flooding, but just now noticed the log from NetworkManager

Edit: Figured out the error from dbus and fixed it in 1.18.0-1.2
