random hardlocks!

[Aroon Pahwa]

recently ive been experiencing some random hardlocks.  the only thing
ive noticed is that im usually scrolling through something when it
happens.  sometimes in firefox, sometimes a PDF file.  The problem
isn't reproduceable.  What log files should i post to help with debug?

I've noticed that the following lines are repeated many many many
times all over my /var/log/syslog file:

Oct 11 15:37:01 localhost postfix/local[4615]: fatal: open database
/etc/aliases.db: No such file or directory
Oct 11 15:37:02 localhost postfix/master[3770]: warning: process
/usr/lib/postfix/local pid 4615 exit status 1
Oct 11 15:37:02 localhost postfix/master[3770]: warning:
/usr/lib/postfix/local: bad command startup -- throttling

i have no idea what that means but they are also present right before
my last hardlock.  any and all help is appreciated!
