DirectoryService still eats 190% CPU, HELP!

Hi all

A few months ago many users reported problems with directoryservice eating 190% CPU and for most upgrading to 10.5.2 seems to have done the trick: http://discussions.apple.com/thread.jspa?threadID=1211429

But not for me, I have tried everything I can think of. This tip didnt work:

And neither did copying the program file /sbin/DirectoryService from a friends computer nor running all maintanence tasts in Onyx.

If I start in "safe boot" mode, everything works fine.

The link below shows an Instrument snapshot of DirectoryService in action.

Does anyone have any suggestions?

MacBook Pro, Mac Mini, PowerBook 12", iMac G4 17", Mac OS X (10.5.1)

Anyone have any clue why this is happening to me or what I should do to fix this?

This only affects my Mac Mini at work but not my MacBook Pro at home.

I doubt that 10.5.2 fixes it for most.
The problem is intermittent and only SEEMS to be fixed till it happens again.
I only see it every week or so.
It can clear itself if you wait a while, but there can be other strangeness so a reboot is probably a good idea anyway.
I suspect a memory management problem.

Thanks for your replay and it is also good to learn I'm not alone.

I have menumeters installed so I continously monitor the CPU load. The DirectoryService bug is always present with increased CPU load every 10 seconds however only some of the time it reaches very high CPU load. ATM the peakes at about 20% for less than a second but it can consume almost all CPU power for 8-9 seconds every 10 seconds when it is really bad.

Rebooting does not help though, booting in "safe" mode does.
