Parental controls floods system.log with errors

Question

I was digging around for fun, and I found that the system.log was FLOODED with errors. Here's an example.

How big would an average system.log file be, and would it get "cleaned out" periodically by monthly processes or something like that? Here is my ls -l | grep system.log.

I have had my computer for just about 2 years. If there is a problem, I would appreciate your thoughts and help.

Answer 1

See if you can find the Parental Controls activity log file. Make sure it's not on a full volume, make sure it's not corrupt (try moving it aside or deleting it and letting the system recreate it), and make sure it has the right permissions (perhaps run a "Repair Permissions" on that volume from Disk Utility)

See the following answer for more information about these files. How can I view Mac OS X Parental Control files with format .data?

The more I read through that other question and answer, the more convinced I am that one or more of your parental controls log files (which are actually CoreData .data files, not plain text logs) are corrupt.
