Periodically I find the yumBackend python script of packagekit really slows down my CentOS 7 system. I don’t invoke anything myself which starts it and I find nothing in crontab which does either, except perhaps
/etc/cron.hourly/0yum-hourly.cron. But I can’t be sure that is the culprit. I don’t find anything at http://www.freedesktop.org/software/PackageKit which helps me to debug this. Would someone point me in a useful direction so that I can find out what /usr/share/PackageKit/helpers/yum/yumBackend.py is doing, why it is doing it, and how it can be controlled? Many thanks….Nick
