Had a bit of a scare today on this dev machine

Had a freeze up... a complete lock of the system and it sounded as if a 777 was trying to take off out of the back of the tower... I noticed CPU was maxed out at 100% and the temp of the CPU (FUCK CONKY) at 79F when it normally sits at 42F

Something was bad wrong... Only thing new was the latest SID updates that included a new kernel updated last night ... 4.2.0-1-amd64 #1 SMP Debian 4.2.1-2

Shut it down and on a reboot I got the message:

Code: [Select]
Xsession: warning: unable to write to /tmp; xsession may exit with an error
and no X to log into

Doing a quick search with ncdu showed the following /var/logs each at 18.9G and my root drive maxed out

Code: [Select]
kernel
messages
syslog

I purged these and rebooted back to the dev environment with no issues.  I have no idea what started it and since the reboot those logs and the CPU is normal again

This is for informational purposes... anyone else see it please report it here

Thanks

Seems this was all related to the latest kernel and VirtualBox 4.3 not liking it... I installed 5.04 VirtualBox and all seems to be well now

Yup, VB 5 solved a lot of kernel issues. I got it a while ago and my VMs are happy again.
