Description John Bobberson 2016-06-30 01:54:30 UTC

I've attached dmesg output. My system will randomly just run out of memory and start killing processes (usually Virtualbox if there is a vm running). This causes the machine to come to a screeching halt. Its a huge problem. I feel like intel just doesn't care about making quality drivers. This machine doesn't play games all I do is run a browser and xscreensaver. It seems the screensavers will eventually cause the system to explode for no real reason.

Another thing that might be useful to know is that I run evilwm. Very minimalist.

Hardware info: 
Linux thebox 4.4.6 #2 SMP Mon Apr 25 21:58:33 EDT 2016 x86_64 Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz GenuineIntel GNU/Linux

MemTotal:       16267892 kB

Let me know what other information is useful.

Perhaps instead of shooting the messenger, you would care to find the culprit who is using all of your memory. At the time of death, all GPU users have 45MiB of memory allocated and in use (of which 8MiB is being used by the hardware and we cannot recover).

What can I do to get you the information you need? The only application that should be using GPU memory are the xscreensavers I'd think. Maybe the screensaver on the VM as well. Firefox, via flash, definitely uses the GPU as well now that I think about it.

I don't think those programs are misbehaving as everyone I talk to uses them without these problems. Might there not be a bug where memory isn't properly freed?

My driver version is: x11-drivers/xf86-video-intel 2.99.917-r2
