DirectoryService hogging cpu

by cmarknrr - 1/6/11 1:40 AM

Everything is running very, very slowly. In the Terminal, top shows me that process 15, DirectoryService, is using between 45 and 248%(!) of my cpu, and hdiutil is also using much more than I expect. What is causing this, and, more importantly, how can I make it stop. It is making my computer unusable.

It doesn't seem to matter what applications are running or if I have Web Sharing on or off. I suspected it was the flood of attempted logins from having Web Sharing on, but turning it off doesn't make any difference.

First thing I'd do

First thing I'd do is boot from the install DVD. You won't be reinstalling the OS, just going one or two screens in until the menu bar appears and you can run Disk Utility from the Utilities menu.

Run both a repair permissions and repair disk operation. This has the dual benefit of finding and repairing any filesystem related errors which may be resulting in your problem, and putting your HDD through a small stress test to see if it's performing properly.

I did all that and it looks like it helps; although there are still times when DirectoryService takes over, it doesn't stay pegged for long.
