MySql keeps dying on me

I need help troubleshooting this…. Maybe you can see a clue that I missed? Here are the facts, as I know them. Any help interpreting this would be greatly appreciated!

$ sudo /sbin/service mysqld status

mysqld dead but subsys locked

$ df

Filesystem 1K-blocks Used Available Use% Mounted on

/dev/xvda 16255928 12518040 3077288 81% /

$ ps aux | grep mysqld

502 30323 0.0 0.0 284 56 ttyp0 D+ 17:07 0:00 grep mysqld

And below follows the last 100 lines of /var/logs/mysqld.log:
