I ran iCal Server + iCal in a test environment on a older Xserve--Dual G4 1GHz 2GB RAM Mac OS X Server 10.5.5--in this test environment with only a couple of test users and I noticed a significant increase in CPU activity due to iCal but it seemed that it wasn't something the server couldn't handle. A month later when I rolled out the service to 60+ users the server was brought to its knees. It ramped up to 100% CPU usage as more users logged in and by about 11AM that business day it ceased to be functional. Anyone trying to connect timed out before they received updates. I have not been able to track down any specifics as far as something I can "fix" to prevent this problem as my iCal Server install is Apple default and other than running the CPU load at 100% there was not a single error reported/logged. I'm going to use brute force to work around the issue but I would like to find a better approach. I am going to try to roll out this service again later today/tomorrow but hosted on a brand new Xserve 3.0GHz Quad-Core Intel Xeon 16GB RAM (I'm lucky in that I work for a bunch of lawyers). I'll let you know what I find out and/or what happens. On Dec 6, 2008, at 11:11 AM, Louis ROMERO wrote:
Hello,
I have a 10.5.5 Mac OS X Server and the iCal Server is on. I have a problem, that happend twice, so I guess there is something.
On time, the CPU was at 100%, taken by the User, but I couldn't see what was wrong in Activity Monitor or top, because the step of measures was to large : I found that there were several small Python processes that were launched and stopped constantly !
I tried to know where they came from. I stopped services one after another, and found out it was iCal : 10% CPU after that.
Today, I had the same problem.
The only thing I did today with iCal Servr was augmenting a LDAP record in the OpenDirectory. I just chose the calendar to be synced with.
Where dos this come from ?
