Hi all,

I had two random freezes too. One after a screenlock and the second one
during using Chromium. The second freeze wasn't a complete one. Mouse
moves were delayed approx. 30s and were very stuttering. I only could do
a hard reset.

I noticed, that despite my memory isn't used completly (3GB/4GB) 50% of
my swap space are used. Further I see chromium uses a lot of swap space
(approx. 450MB). I don't know if this is an indication of the problem. I
never checked the usage of swap before.

My setup:
i3 4.12
py3status 3.1rc0
Chromium 53
xautolock 2.2


I've had 2 lockups during the last week, too, but I wasn't on the machine when they happened. Not sure if it's related, but in my case, it was a desktop machine and the whole system froze (sshd wasn't answering, either). I'm not seing any indication of what's happening in journalctl, other than journalctl stops recording anything at a certain time.

I've also see the increased swap usage over the last few months. I went through the swap page at https://wiki.archlinux.org/index.php/Swap and https://rudd-o.com/linux-and-free-software/tales-from-responsivenessland-why-linux-feels-slow-and-how-to-fix-that and saw no change. Every morning I come down to something like this:

$ free -m
total used free shared buff/cache available
Mem:          15998        3345         421         240 12230       12080
Swap:         16383        1374       15009

And all my apps appear to be swapped out (Chromium, Thunderbird, even a locked KeePassX). I do run backups overnight and imagine that the buff/cache is filling up with directories and pushing out the actual apps. I'm thinking about disabling swap at this point, since I don't really do anything with the box that requires swap space, or approaches 16G of ram.
