Hi,

There are some things that makes my machine to freeze

1. I've noticed that if I have some heavy CPU usage (ex. running many VMs or tensorflow training or having tracker-miner-fs working in background)
while typing somewhere (firefox, geany, ...etc) a flood of keystrokes is send to the application (I know this because when I restore session after firefox crash I see a million s in location bar, if my last attempt was to type scholar.google.com)
it could be related to libinput or something

so I got a crash not because of the heavy cpu but because of the flood of key strokes passed to applications

2. tracker-miner-fs which can't be turned off and
I've spin disks not SSDs but my friends with SSDs also suffer from same thing

I've a lot of data in my ~/Downloads (many projects, git repos, ...etc.)
It seems that all options to turn it off are outdated < https://ask.fedoraproject.org/en/question/9822/how-do-i-disable-tracker-in-gnome/

It seems that tracker-miner does not respect configuration

gsettings set org.freedesktop.Tracker.Miner.Files crawling-interval -2

in should_crawl function it checks if interval is -2 it supposed to get disabled


3. I got a flood of logs in /var/log/messages* and journal here is a summary
