Tables keep crashing and corrupting

Hi!

I have a 64bits Ubuntu server 12.04 running a '5.5.31-0ubuntu0.12.04.2-log' MySQL serevr.

My server keeps crashing every other day and the apps that depend on this DB layer also freeze as consequence of DB unavailability.

Today I found this kind of error repeats itself several times in my error.log:
[ERROR] /usr/sbin/mysqld: Incorrect key file for table ...

people online are suggesting disk capacity is the root cause but I have space on my partititons... The only partition that shows high usage under crashing circumstances is the /dev/sdc where the /var/log folder is mounted, I don't understand this behaviour.

Furthermore, i share below info on my partition scheme.

If you need any more information, I will gladly share it.

Best regards,
Sebastião
