Ubuntu 16.04 /usr/bin/gnome-software --gapplication-service 100% CPU consumption

From time to time process /usr/bin/gnome-software --gapplication-service starts consuming 100% of one of my cores. It is fixed if I reboot, or kill it with kill.

Is there a way to understand why this is happening? I want to create bug report. I could not find anything related in /var/log/.

I think you need to look into the file /var/log/kern.log its about the internals.

I have had one VM log some errors there, I snapshotted my VM and redeployed it the errors never happened again.

You may have a faulty core or overheating CPU, just my best guess.

I had the same issue and running journalctl -f to access the system logs explained it all: org.gnome.Software was running in loop because of a "corrupted package cache file", inviting me to run apt-get update to solve the issue

The logs (in French, sorry):

org.gnome.Software[2565]: E: Le fichier de cache des paquets est corrompu
org.gnome.Software[2565]: (gnome-software:3153): Gs-WARNING **: failed to call gs_plugin_refine_app on apt: apt DB load failed: error while initialising
org.gnome.Software[2565]: E: Impossible de traiter le fichier /var/lib/apt/lists/ppa.launchpad.net_webupd8team_atom_ubuntu_dists_xenial_main_binary-all_Packages (1)

I just killed the process and moved on, running apt-get commands doesn't produce any error and I'm not using gnome software center anyway. I would like to find a way to fully disable it though
