Interesting, I am having a very similar issue. Server has hung 3 times this week, where it becomes completely unresponsive, wont even respond to ping. Issue most recently occured while starting a minecraft server in a windows VM, but has occurred seemingly randomly at other times. I ran memtest86 and it passed, so I can rule out memory, but my syslog is full of the same thing so I have no idea what's going on.
