I've been running that for for over 10yrs now since way back in my
Mandrake days. I'll take a look at offlineimap and see how it is.

I took a look at startup processes on boot and it shows networkmanager
set to 'no' and wicd to 'yes' though looking at top I see that both are
running. I never noticed was wicd used in 14.04LTS?

Found nothing useful in /var/crash however I did install Variety on the
29th of Aug

Start-Date: 2016-08-28  21:33:57
Commandline: apt-get install variety

and the first oom error was on the 29th at 03:24am. Hmm, I'm wondering
now if that's maybe the issue? But, looking at the oom I got this
morning - https://pastebin.com/3y7DP4Jq I've been running top with this
command line - top -d 30 -p 26224 -p 26485 -p 21041 -p 2957 -p 2258 -p
3543 -b > top.txt of course I had to change it when the oom closed out
Evo. I stopped Variety last night at 8:23pm, no oom during the night, I
restarted it at 8:10am this morning and the oom came at 10:37am this
morning. Since I have Variety set to not only use wallpaper images in
my ~/Wallpaper folder but to download images from various sites also
I'll stop the downloading first to see what happens. 

I had to stop and take care of some things but awhile after I set
Variety to only use my wallpaper and not grab quotes from the internet
I had another oom - https://pastebin.com/05hVgtJK I'm going to
completely stop Variety and see what happens. That's the only logical
application I can think of that may be the cause. If so I really need
to contact the author and let him know.
