Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

Syslogd makes high CPU Load and standby mode doesn´t work.

After updating to Leopard I see high CPU Load caused by syslogd daemon(40%-80%) and my MacBook has problems with standby mode. After stopping the white LED lights and CPU fan speeds up. Is there any chance to fix these problems?

MacBook, Mac OS X (10.5), 2GIG RAM, 160 GIG HDD, USB & Firewire Devices.

Ahh, yes - I had an error at around 7:30AM this morning, viewing a quicktime file - which wrote to the log over 40,000 lines.

This error with syslogd only occurred at around 1PM this afternoon, and still persists after removing the log file, rebooting the system, and syslogd starting a fresh log file.

So I don't think the size of the log file has anything to do with it.

I have observed that whenever syslogd writes to system.log, my CPU useage spikes, so it's got something to do with that. How to fix it? I have no idea (wait for 10.5.1 I suppose)

I talked to Apple about it today. The guy I talked to didn't know anything about it but put me on hold to ask someone else. He the came back and gave me some things to try. None helped but he thanked me for letting them know and said to check back in a week or so as they would be investigation it. I also provided him with the URL to this post. We will see. Cross your fingers.

same issue here - after updating to leopard every time syslogd logs something to system.log
the cpu and usage and fan goes up insanly.

the only "workaround" i found so far, is to disable the syslogd by typing
"sudo launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist"
in terminal.



of course this isn't a proper solution but at least this will protect me from becoming deaf due to the fan 😉

"sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist"
will start the syslogd (and therefore the high cpu usage) again

Maybe woth a try is to reeinstall leopard with the "install and archive" option.
After i've done the leopard installation again with this option - syslogd works again as expcted.
Happily this keeps all applications and setting - so there is no reaseon to worry.
Now the cpu usage doesn't go up when a application logs to system.log

Syslogd makes high CPU Load and standby mode doesn´t work.
