iCal beachballing a lot

[Jethryn Freyman]

Hey guys. Got an iCal problem here.

Quite frequently, like maybe 20% of the time I do a task (create an event, scroll between weeks, edit and event), I get a hang for a second, then a beachball for a second, then it returns to normal.

Checked the activity monitor, my CPU usage for iCal maxes out on both CPUs while this is happening.

I've got about 8 calendars with an average of about 2 events per day that go back 5 years, plus another 20 or so calendars that aren't viewable (they're old and I unchecked their checkboxes), and about 10 viewable To Do items (they are set to hide automatically after being completed for 1 day) and I usually make about 2 per day.

Running OS X 10.5.8 on a dual 1.8GHz Power Mac G5. 3GB of RAM (iCal uses about 70MB and 1GB of virtual memory, no paging) and a 7,200rpm hard disk (500GB free, no usage of the drive while beachballing.)

Any help or anybody seen this before?

Thanks 🙂

Do any of the calendars have a lot of recurring appointments?

No - none at all.

OK, I used the Developer Tools "Spin Control" to catch a hang and got a report on it.

I can't make much of it myself....
