I have sometimes experienced this kind of thing and agree it is usually
indicative of faulty hardware, however have also found it can be caused
by graphics drivers, particularly if the box has just gone through a
major distribution upgrade. These days it's the thing I (slightly)
worry about causing some inconvenience on an upgrade. Happened on a
couple of ubuntu boxes I took to 14.04 LTS recently.
Sadly, the fix isn't necessarily ensuring the latest drivers are
installed, it can mean going back a version. It's a bit random, and
somewhat frustrating . . .
Also sometimes, the fix for issues following a distro upgrade is running
the apt-get update/upgrade (equivalent for Mageia) as this might pick up
something missed first time round?
Good luck with it all :)

Thanks for your replies everyone. I ran memtester for abt 5 hrs
yesterday without noticing any thing. Box has not been altered for
over a year. Gut feeling is that Mageia 4 has a faulty app which runs
before login. No probs before installing Mageia 4. Not related to wifi
problems. Opera was a dog trying to run facebook and thought at 1st
this was the problem but not so so have gone over to firefox with a
far better response.
Currently running Mageia 2 on a 2nd hd in the same box. Going out now
so will shut all apps down and leave memtest86 alone running
thanks

Hi all, could I have some words of wisdom pls re this problem.
Every so often the box just stops and screen freezes. No mouse, no
keyboard. I have to switch off then reboot. The 2nd last time this
happened I had booted, got to the login screen and left it idle for a
time. Screen was frozen so tried to login from another box but wifi had
not started (naturally). Next time I logged in & went straight to kde
system guard to see what was running. The last item started was sleep
with cmd "K sleep 60". There was another app started by mgaapplet but
was a zombie so I deleted mgaapplet & crashed the box. Until now I
thought it was an app I was running but not now.
Any suggestions as to where to look to solve this problem are most
welcome.
uname -a = "Linux TheBox 3.12.20-server-1.mga4 #1 SMP Fri May 16

Memory currently 501.4mg/1.5gb. sleep is still running with the highest
pid.
TIA
