OS X :: Runaway Syslog Eats Up CPU?
Dec 30, 2009
My fiancee's Macbook is having an issue where the syslog will take over an incredible amount of the CPU (Activity Monitor frequently has it pegged in the high-90s-percentile) and run continuously, making the machine heat up and causing the fans to run continuously, which drains the battery quickly. I've done a bunch of searches on it, but the only fixes I've found refer to syslogd (which is not causing problems on her machine), not syslog.
I've still tried to apply a number of those fixes which have all failed, including manually killing the process in Activity Monitor (which caused huge Airport/Time Capsule problems on my own MBP) and deleting the asl.db file (which didn't help at all)... kind of running out of options here and getting frustrated.She's running OS 10.5.8 on a 2.16 GHz chip with 1GB of RAM.

I'm dumb and late last night decided to follow the directions in this article:(URL) Using Lingon, I modified the startup parameters of "syslog" from "/usr/sbin/syslogd" to "/usr/sbin/syslogd -c 3 a". Of course by fiddling around with things I shouldnt have, my computer wont boot past the gray apple screen or past "waiting for dsmos" in verbose mode. I would backup from Time Machine, but my most recent backup doesnt have several important large work files that wouldnt fit in my Dropbox. I realize it was stupid to mess around with this without backing up, but feel free to flog away! I've run diskutil, verified/repaired, run fsck -fy from single user mode, reset pram, wont boot to safe mode, etc.
My question: is it possible to edit the startup parameters of "syslog" from the command line in single user mode? If so, how? AND Is it possible to reinstall OS X system files from the boot disc without erasing my entire disk?

Randomly on my computer I noticed very high CPU use while the computer was otherwise idle. I have narrowed it to the launchd and syslogd processes, taking up roughly 85% of my CPU for no good reason. I do have a TM backup that I could restore from, but that takes a while, so is there any way I could make them stop? (Already tried quitting from Activity monitor, it simply restarted my computer and didn't fix the problem)EDIT- Nevermind, it just went away on its own. Weird.

I have this NAS drive (a 1 TB QNAP TS-209 Pro) where I keep most of my files, so I want to auto-mount two shares on that drive upon login. In Windows, it was a set-and-forget type thing. In OS X it was a little harder, I eventually got there by disabling the firewall and placing the NAS shares under Login Items and checking "Hide". This works fine on my old Mac Mini and my iMac, but on my new MBP I get some really crazy stuff. Two processes called "coreservicesd" and "System Services" (under the parent "launchd") are taking up 40-50% CPU each. This goes on for 10 minutes before it settles down, by which time some 10-15% have been drained from the battery.
(On login the estimate is 2 hours left on a fully charged MBP 17"... it jumps to 5-6 hours as soon as the CPU insanity stops). If I unmount the drive, the CPU hogging stops immediately. I can then re-mount it without getting the crazy CPU load phenomenon. I can also remove it from Login Items and mount manually through Finder with no problems. As soon as I place it under Login Items again, CPU usage shoots up to 40-50% again, this time System Preferences is listed as the culprit. Any ideas why the CPU is going berserk from connecting to a simple network drive via smb, and only when the volumes are included in Login Items? The problem is specific to this week-old computer, so let's not blame the NAS drive just yet.

I booted up my MacBook this morning and a grey progress bar appeared at the bottom along with the normal spinner. Well after this update installed (thats what Im thinking it was) it warned me I had no disk space left. A had 57% last night! What ever that progress bar did ate up 38.7GBs of space! If anyone has help to get back my disk space it would be nice. I only have 500MBs left.

I use a Fortigate router and would like to track what sites are visited by the people using my network. Was told if you set up a syslog server we can dump the information from the fortigate to it.
I am using a MacMini server 10.6 and would like to know the best way of going about this. Is there a program out there I can use?

I recently did a Lion clean install and since then im having this wierd issue..I already saw some cases that the kernel_task was eating too much cpu but that was random and caused by flash player.. mine is different.. it only happens when i have less than 5% battery and it stops when i connect the magsafe. I already tried PRAM reset.. already tried uninstall flash player but with no luck. What can i do ?

Problem is pretty much summarized in the topic line. Had a distnoted process that was eating up all my CPU. Killed it in Activity Monitor, and the computer hung. Forced a restart, and it won't...restart. Tried a safe reboot, resetting the NRAM...no joy.
2012 (I believe) iMac running the latest version of OS X Mavericks.
