MDK 10 random restarts?

[PPPP]

I recently installed MDK10 Official and it seems to have restared twice by itself. it seems to be restarting after being on for 3 days.

These are the last entries before the reboot:

Jun  2 07:01:01 localhost kernel: VFS: busy inodes on changed media.
Jun  2 07:01:33 localhost last message repeated 16 times
Jun  2 07:02:35 localhost last message repeated 31 times
Jun  2 07:03:37 localhost last message repeated 31 times
Jun  2 07:04:39 localhost last message repeated 31 times
Jun  2 07:05:40 localhost last message repeated 30 times
Jun  2 07:06:42 localhost last message repeated 31 times
Jun  2 07:07:44 localhost last message repeated 31 times
Jun  2 07:08:46 localhost last message repeated 31 times
Jun  2 07:09:48 localhost last message repeated 31 times
Jun  2 07:10:50 localhost last message repeated 31 times
Jun  2 07:11:52 localhost last message repeated 31 times
Jun  2 07:13:19 localhost syslogd 1.4.1: restart.

 

And here I found something rather strange looking:

Jun  2 04:05:31 localhost : Security Warning: World Writable files found :
