Guys, I’ve been trying to solve this issue for months now. I’ve ready everything I could find on the internet, and tried everything and nothing helps. Sure it’ll stop the process but then a few hours later its back again. Has anyone found a permanent solution for this? I tried getting help at Apple store but they are such Apple Nazis that they refuse to admit there is even a syslog issue. Fucking lame.

Thankyou! After following these instructions my Mac finally started responding after this happened a few days ago – I suppose this could be put into a cron script to make this problem fix itself before it happens?

This Problem returns frequently on my eMac.
I can solve it with the following commands by Julian and DeeJan.
Is it posiible to buidl a script that I can doubleclick, so that i don’t have to type it manually every time?
Thank you, Felix.

I also had to delete /var/log/system.log:

sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd

100% CPU again!

sudo launchctl stop com.apple.syslogd
sudo rm /var/log/system.log
sudo touch /var/log/system.log
sudo launchctl start com.apple.syslogd

syslogd is idling normally!

Hi Tim,

that’s correct, syslogd gets the hiccups when its database file is corrupted. Delete it and syslogd starts over, no problem remaining.

Why is it that the best source of information like is always OUTSIDE the Apple website. Woke up this morning to my MacBook Pro fans spinning like crazy, saw the CPU usage of SyslogD, and did a web search, found this page, problem solved.

Would be curious to know what exactly is happening that causes this, is the file corrupt or something?

Anyway, thanks for the tip!

I’m so glad i got my computer back! I was so frustrated at how my imac G5 was so sluggish, and was considering buying a new imac.

Thanks so much!

It is such a glaring flaw in OSX. One day it simply rendered my computer unusable and even the 10.5.5 update preserved this crap syslogd. Your commands worked beautifully – thanks! Now, Apple is really turning into Microsoft at its worst: there used to be registry and now I am supposed to fix OSX by typing some obscure commands.
I guess the time when computers can actually be relied upon is still pretty far off…

Hi Eduardo,

it’s okay to stop syslogd temporarily, but since it is an essential part of the system it’s not a good idea to stop it permanently—you don’t want to prevent several services from the system’s core from running.

Thanks for this, dam syslogd was driving me mad, thought there was not reason for my macbook pro running of such high fan speeds all the time.

Though the process only works for me if I stop the syslogd…. will that be bad for my system?
And is there any way to stop it permanently?

Thank you. I have an old eMac and this trouble was seriously slowing down my computer. Now I don’t have to think on buying a new iMac, so… thanks?
