Both memory and load are quite high, around 40-50% average usage for  
CPU and 80% phys memory used.

Here is one of the problem calendars:
access.log
[12/Feb/2009:00:02:39 +0200] "PROPFIND /calendars/__uids__/ 
819B6FB2-066B-446C-854F-DC14DDD937D8/ HTTP/1.1" 207 5184 "-" "DAVKit/ 
3.0.6 (653); CalendarStore/3.0.6 (847); iCal/3.0.6 (1273); Mac OS X/ 
10.5.6 (9G55)" [4048.2 ms]

error.log
2009-02-12 00:02:38+0100 [-] [caldav-8009]  [AMP,client] PROPFIND / 
calendars/__uids__/819B6FB2-066B-446C-854F-DC14DDD937D8/ HTTP/1.1

iCal client:
2/12/09 12:04 iCal[4703] CalCalDAVCalendarSource: Error  
Domain=AYErrorDomain Code=2 UserInfo=0x167c7a20 "Async Operation timed

819B6FB2-066B-446C-854F-DC14DDD937D8/calendar/ responded with the error:

many PROPFINDs are less then 100ms all problem ones are 3000ms+

I will look into possible network issues.

Thanks!
