ical maxing out cpu

Question

ical maxing out cpu

Recently iCal has started exhibiting some weird behavior. For no apparent reason, it starts pegging my cpu at 100%. Console is showing the message:

"Unexpected EOF, returning last token as fallback"

over 20 times per second for about 7 minutes, and then stops. It does this once an hour.

I also see in console another ical error:

"VTIMEZONE does not match System Time Zone"

followed by a handful of date/times that look like the start and stop of Daylight Savings from 2006-2008. This might be completely unrelated, but there it is just in case.

The only thing I've done differently lately is to start syncing to a google calendar, but that was weeks ago, and this behavior seems much newer than that.

Any ideas?

MacBook (2009), Mac OS X (10.6.4)

Welcome to Apple Discussions,

Go to Apple Menu > System Preferences > Language & Text > Formats >Region -- Make sure this says United States. (I'm assuming here that you are running 10.6.4. Your profile does not say.)

If that is not the issue:
First make an iCal backup, File > Export > Archive.

Remove the following to the trash and restart your computer:
Home > Library > Caches
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
__NOTE: Removing these files will remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.

Once the computer is back up and running re-add the Google account to iCal > Preferences > Accounts and test.

Hope that helps.
