I use Chrome Version 71.0.3578.98 (Official Build) (64-bit)
I have 10 Chrome extensions but none of them is called zygote
"Software is up to date"- Ubuntu Software
I do not think I have any Gnome extensions, not sure how to check it
gnome-shell --version
GNOME Shell 3.28.3
Chrome active extensions:
- delugesiphon 0.72.5
- Google Docs Offline 1.7
- IP Address and Domain Information 4.0.1.0
- Nano Adblocker 1.0.0.83 - just installed, should not have caused issue
- Nano Defender 15.0.0.81 - just installed
- Tampermonkey 4.7.54 - just installed
- User-Agent Switcher for Google Chrome 1.9.3
- Docs 0.10
- Sheets 1.2
- Slides 0.10
This solved it
ps ax | grep zygote
62183 tty2 S+ 0:00 /opt/brave.com/brave/brave --type=zygote
62185 tty2 S+ 0:00 /opt/brave.com/brave/brave --type=zygote
62781 pts/9 S+ 0:00 grep --color=auto zygote
kill 62183
From the comments...
It looks like Chrome, or one of its extensions that you've installed, are causing your crazy syslog files.
Either:
Temporarily disable ALL Chrome extensions and see if the problem still occurs.
Temporarily run with Firefox and see if the problem still occurs.
