Are you using ECC RAM?
If you're not, then you'll see some checksumming/parity calculation errors.
Is this a huge problem? I guess it could be when you consider how important
your data is to you.
Your ZPool(s) could get really screwed up if you're getting checksumming
errors.

A cronjob to scrub the system isn't a bad idea, I guess you'd have to make
sure that nothing is going to try and use the system during the scrubbing
process though.
