Hi to the new updaters, :-) I found this to happen with several instances of chrome, or with file operations over big files in combination. I've filed a bug report that was confirmed a couple of years ago: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1504914
One thing that helped me to avoid some hang if I manage to do it promptly was to go su and use the drop_caches $ sudo su $ free -h && sync && echo 3 > /proc/sys/vm/drop_caches && free -h But this works temporarily and as long as I don't keep with many instances or big files accesses.
