syslogd bug

I just did a clean install of Leopard after a hard drive replacement on my trusty ol’ 2003 PowerBook G4 — runs like a champ, actually — and I’ve been seeing these strange CPU spikes. From what I can tell, it’s a bug in syslogd, the logging daemon in 10.5. Until it’s fixed in the upcoming Mac OS X 10.5.2 (hope hope), you can do this:
sudo launchctl stop com.apple.syslogd
…to stop syslogd from spiking your CPU.

Time Machine and Spotlight can often cause this behavior in syslogd. I fixed it by turning Time Machine Off, then On, then reboot.
