This happened because guest used lots of memory on NUMA machine.

The guest used lots of memory on NUMA machine. Turned out KSM merged some of the processes pages causing the particular processes to crawl.

I had the same problem, the laptop Dell Studio 1569 have been freezing after 3-4 hours of work (ubuntu 13.04 amd64). I tried to install bcmwl-kernel 6.30.223, disabled apport, disabled Intel SpeedStep, used acpi=off noapic kernel args, to no avail. Upgraded kernel to version 3.10.0.6 (taken from ubuntu saucy) and worked for 15 hours already.

I've tried to gather as much information as possible. If there is anyting else I can do, please ask. UPDATE: I'm now using the open source videocard drivers, and now when the system crashes I get a kernel panic (unfortunatelly I seem to be unable to find the full message in a log, if there are any at all). I'm not sure if the kernel panic is the same crash as under the other videocard drivers, but the effect appears to be the same, with the exception that the screen does not freeze, but switches to text-mode (still accepts no keyboard input). --- ApportVersion: 2.9.2-0ubuntu8 Architecture: i386 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC0: elco 1953 F pulseaudio CRDA: country NL: (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ 40), (N/A, 20), NO-OUTDOOR (5250 - 5330 @ 40), (N/A, 20), NO-OUTDOOR, DFS (5490 - 5710 @ 40), (N/A, 27), DFS DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=d4e85ebe-079f-44d5-af90-efd4595f5095 InstallationDate: Installed on 2013-04-26 (0 days ago) InstallationMedia: Ubuntu 13.04 Raring Ringtail - Release i386 (20130424) MachineType: Dell Inc.
