This has happened twice now.
I'm on an AWS EC2 m3.large instance with the official Ubuntu AMI ami-776d9700.
# cat /proc/version_signature
Ubuntu 3.13.0-32.57-generic 3.13.11.4
After running for many days, the machine locked up with the below messages appearing in the terminal. The machine would respond to ping but not SSH or HTTP requests. The machine has one BTRFS volume which is 87% full and lives on an Logical Volume Manager (LVM) block device on top of one Amazon Elastic Block Store (EBS) device.
Error messages after first reboot:
