'airport' process chewing up CPU on boot?

I'm having a weird problem. I've had my MacBook for about a month, but this problem has only been happening in the last few days. Before I begin, I'm 100% up to date and repaired permissions.
When I boot up my computer, the fans start going full speed and don't seem to slow down. I open up the activity monitor and sort my processor usage. At around 98%, a process called airport is chewing up the CPU. I end up having to Force Quit to make it stop and to make the computer cool off. Oddly enough the actual AirPort Express still works with this process killed.
What is this process? Why does it run near 100%? Is it okay for me to kill it? What can I do to prevent this from happening on every boot?

Airport Process utilizing high CPU utilization

I currently have a 13 inch MacBook Pro i7 (2012 version). Recently I upgraded to Mavericks. After using the computer for a day after the upgrade, I began to notice it becoming very hot and the fans running very high. Looking at the running processes i noticed that a process called "airport" was running and utilizing high CPU times causing the heating up and fans running. Once I stopped this process, the laptop went back to operating at normal levels.
Unfortunately this issue began to come back several times....the "airport" process starting at any time and utilizing high CPU utilization....again only by killing this process fixed this issue.
After seeing this behavior over several days, I decised to wipe the drive and install a clean copy of Mavericks in the computer. Thought here was that possibly something did not carry over correctly from the upgrade from Mountain Lion to Mavericks. Unfortunely this did not correct the issue with the "airport" process as it still is continiung to launch at any time and spike the processor until I manually kill the process.
I do not recall this issue occuring while running Mountain Lion so it seems to be specific to Mavericks at this point.
I was hoping to hear if any other have experienced this type of issues while running Mavericks.

You should be able to find the information you are looking for from the default Total CPU Utilization Percentage monitor. This monitor has a built in diagnostic task that will kick off when an alert is triggered to list the top cpu consuming processes.
To find which processes were causing CPU to spike, simply review the State Change Events history in health explorer for the machine that was affected, for the Total CPU Utilization Percentage monitor. I have modified my second screen shot
to remove machine names, but you should get the idea. If a cpu monitor went from green to red, it will run the diagnostic task and list the process information and cpu usage at the time of the alert under state change events.

Airport process consuming 90-100% of cpu time

I have first gen Macbook Pro, 2Ghz. Just in the last day or so, I've noticed that the "airport" process is pretty well using up one of my CPU cores. I can kill it and I don't notice any problems.
I have read the article explaining that third party VPN software can cause this, but I have no such software installed.
edit: I've noticed that it does this when first booted. If I use airport status in the menu bar to turn off the airport card and then turn it back on, the cpu usage goes back down. Anyone know what might cause this?

"airport" process uses all of the memory an cpu

After I reinstalled my MacBook and updated to the latest version of Tiger (10.4.8) my airport network behaves very strange. When I boot my MacBook or disconnect/connect my Airport network a process called "airport" is consuming all the CPU and memory. It uses one core exclusivly and gows to 1,2 GByte of RAM (even more virtual Memory). This slows down the macbook to almost still and heats up the CPU.
The only thing I can do is to kill the process. Then everything works fine. But this is annoying.
It seems to make no difference if I use a wireless LAN or not. When airport is enabled then this bug occurs.

On this thread,
http://discussions.apple.com/thread.jspa?messageID=349
2852, people that have Check Point Software's
SecureClient are reporting the airport process using
~95% of CPU time.
I had SecureClient installed and I can confirm that
if you uninstall SecureClient, the airport process
works normally again. I don't know if this is the
only source of this problem, but if you happen to
have SecureClient, then you might want to uninstall
and confirm if this solves your problem.
Also I would be curious if anyone is having this
problem that has never had SecureClient, or any 3rd
party VPN software.
I can confirm that at least some of my problem with the "airport" process was related to VPN software. After uninstalling the Cisco VPN client, problems dramatically reduced. Interestingly, I still have the Checkpoint client installed, but only rarely see problems with "airport".

Memory leak in airport process on Core 2 Duo MBP?

Hello!
I'm having a problem with my MacBook Pro Core 2 Duo (15"). It was slowing down rather rapidly after boot, so I pulled up Activity Monitor and found that the process "airport" had consumed 1.3G of Real Memory and 2G of Virtual Memory, plus 100% of the % CPU. I killed the process and it goes back to normal (importantly, without any impact on the wireless networking).
If I shut the screen and start it up again, it relaunches the airport process and it eats up the memory and processor all over again.
Anyone have any ideas what might be wrong? I've already repaired the permissions.

This is driving me crazy.
Running Win8 x64. i7 8GB X1.
Everything up to date.
I'm extremely careful about extra unneeded startup processes etc.
Recently I'll be going along and notice, gee this is running hot and the fan is running constant.
I notice ntoskrnl.exe is chewing 30% CPU
I reboot and things immediately cool down and ntoskrnl.exe is back down to under 1% CPU
I have been having issues with WIFI (that many folks have, running latest from Intel).
Googling ntoskrnl.exe hogging CPU is a common issue but many kernel level drivers fall under that task.
Some folks blame WIFI drivers. But when in this CPU piggy state if I turn WIFI off with the switch, the CPU is still stuck at 30%.
When I reboot I could go for hours with no issue at all.
This did not used to happen and I'm puzzled, but I have been playing with WIFI drivers and settings (which has also been very frustrating, but I have that "Fixed" by a quirky procedure, but don't know if that is anyway related to this CPU pig thing).

I found the problem and once I did find it I googled for it and found a thread right here about it.

Netbeans(java.exe) chewing up CPU

[Please excuse me if this shows up twice but after make my last post this thread never showed up!]
Hello, everytime I run an emu, no matter which one including wtk, netbeans java.exe starts chewing up lots of CPU time it's like at 98percent and nb comes to a halt and Ihave to wait a few minutes for it to settle down. I really gets bad when I do , "System.out.println()" on a large buffer that really kills it. so I now I can't display large buffers and I have no alternative.
What can I do to stop java.exe from chewing up cpu time when I run and/or print large buffers?
My Environment:
CPU: AMD 64 +3200
MEM: 1GB
OS: XP Pro SP2 (version 5.1 )
EMU: Nokia S60 3rd Ed. / Nokia S40 / Sun WTK 2.5.1
Java: 1.5.0_12
VM: Java Hotspot(TM) Client VM 1.5.0_12-b04
NB Product Ver: Netbeans IDE 5.5.1 (Build 20070422300)
I would appreciate any help!
Thankyou.

ORACLE dispatcher process running high cpu (100%)

Hi:
I'm running Apex 4 on database Oracle 11g 11.2.0.2.0. The cpu consumption is really high after a while. Oracle Dispatcher process goes 100% cpu for very long time.
Anyone here had the same problem? I'm created more dispatchers to workaround this issue but the problem is not solved. At oracle support seams there's a bug about this issue 14106948, but no solution yet.
Anyone with same problem? Any solution?
Thanks
Ricardo

Mdworker process suddenly high CPU usage

Hi All
I've been running Mountain Lion since it was released, upgrading from Lion. I've never had a problem with mdworker until a few days ago when suddenly, the mdworker process started hitting 90% CPU on my iMac.
I've disabled Spotlight, deleted the .Spotlight directories, rebooted the iMac, but each time mdworker . Prior to this, the iMac's CPU temperature was around 43C, with very little CPU usage, but now it is around 60C and 100% across the two cores. The only way to 'get back to normal' is to use :
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
but of course Spotlight doesn't work at all.
I've used 'sudo fs_usage -w -f filesys mdworker' but I can't see anything that mdworker is perhaps choking on.
Does any have any ideas? I'm racking my brain to remember if I did anything different a few days back that might have caused this to happen, but apart from just normal email and web surfing, nothing else springs to mind.
Help!

This solved my questionRe: mdworker process suddenly high CPU usage Nov 28, 2012 1:41 AM (in response to antobal)
In my case it was the BritannicaBookmark.mdimporter that was a PowerPC mdimporter. But it was not in \library\spotlight but inBritannica 12.0/Ultimate Reference Suite.app/Contents/Library/Spotlight.
You can see what spotlight plugin is choking on you by selecting the mdworker process in the Activity monitor and click on Open files and processes.
Sounds helpful, but I don't see "Open files and processes" in Activity Monitor. If I click on inspect, I get a choice to "Sample" processes. I get a system log that is a bit beyond me.

I was having the same problem, and a second level support person at Apple helped me solve the issue today:
Look in the \library\spotlight folders both at your drive root level and your user folder. These folders contain spotlight plugins, with the extension .mdimporter. Some of those plugins, if defective, can make the Spotlight indexing processes to run continuously.
Also sounds helpful, I found .mdimporter files in my system library, but nothing looked unusual. I didn't see a spotlight folder in my user library. I looked in application support and several other places. I used Onyx to repair permissions, rebuild spotlight index, clear caches etc, rebooted, it seems to be OK now.

Java process take 100% cpu

Hello,
I have a webapp running on Tomcat 5.0.28/RHEL 3.0. After some time (approximatively 1 hour), a java process take 100% cpu load and never stop, but the application do nothing.
Some detail on my configuration :
Distribution : Redhat Enterprise Linux 3.0 (updated)
Kernel 2.4.21-37.0.1.ELsmp
Glibc 2.3.2-95.37
JVM : JRockit 1.4.2.08 (the last one)
Tomcat : 5.0.28
Server : 2*Xeon 3GHz HT, 2Go RAM
JVM param : -Xmx:256m -Xms:256m
Thanks for your answers ...

Try taking thread dump (send a SIGQUIT to JRockit using "kill"). If you
get a thread dump, the VM is alive, and it's probably your java program
that's broken. In that case, make a JRA recording to see what's happening:
http://e-docs.bea.com/jrockit/docs142/usingJRA/jra.html
The methods pane is probably what you're looking for.
If you don't get any thread dump when sending a SIGQUIT to JRockit,
come back here.

Which process taking high CPU

Hi
Our environment is having SCOM 2007 R2.
I want to get the details of processes taking high CPU,memory in windows server 2003 , 2008. These details are stored in Opsmgr DatawareHouse ? , can I get in the form of reports? OR any script available.Please help.
Regards
Madhavi

Hi Madhavi,
Run this script on a server and you will get the individual process utilization. I am not sure how you exactly need this.
strComputer = "localhost"
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" _
    & strComputer & "\root\cimv2")
Set colProcesses = objWMIService.ExecQuery _
   ("Select * from Win32_Process")
For Each objProcess in colProcesses
    Wscript.Echo "Process: " & objProcess.Name
    sngProcessTime = (CSng(objProcess.KernelModeTime) + _
        CSng(objProcess.UserModeTime)) / 10000000
    Wscript.Echo "Processor Time: " & sngProcessTime
    Wscript.Echo "Process ID: " & objProcess.ProcessID
    Wscript.Echo "Working Set Size: " _
    & objProcess.WorkingSetSize
    Wscript.Echo "Page File Size: " _
    & objProcess.PageFileUsage
    Wscript.Echo "Page Faults: " & objProcess.PageFaults

Let me know if this helps

50% CPU load @ Boot: nmbd crash and reload bug

I have seen several threads here and around the net about samba on OSX using over 50% of the CPU without showing up in the activity monitor OR in top on the command line. While this is easily solved by unchecking the Windows Sharing service under System Preferences -> Sharing, this is not a fix. It just hides the problem, samba is still broken, and those of us who actually need windows interoperability are left with a machine that gets very hot, has poor battery life, and performs sluggishly.
Don't get me wrong, I am grateful to the people who actually found out what the problem is and how to get around it for a bit, but the problem is not "solved".
I've used *nix flavors for several years now and I have never seen this problem before. After having a MacBook for 8 days, I am now very frustrated.
So, what do we do to FIX the problem? An hour and a half on the phone with Apple Tech Support and I've learned that this problem has persisted through OSX 10.1 - 10.4.6, x86 and PPC. One person in these forums is trying (unsuccessfully I might add) to rebuild samba from scratch (for a different reason, they need ldap support: http://discussions.apple.com/thread.jspa?messageID=2166703

I just diagnosed this problem on my new MacBook. I had seen that suddenly my CPUs would peg for no reason. Finally after a few days of frustrating work trying to identify the offending program I noticed that nmbd would be launched time and time again as a root process and the CPU load would correspond with it, but its process would not be shown consuming the cycles. Looking up what nmbd did I killed Windows file sharing and the problem was resolved. Looks like the program crashes and causes all of the load on the CPUs, but a debugger never comes up or message from the Finder saying it crashed. It was only consuming 1.25megs of RAM on my system before the problem would happen over and over. Looking on my friends MacMini with identical specs to my MacBook, his constantly uses about 3.58 megs of RAM. Process broken on MacBooks only? Dunno...
Yes it *****, but at least I know my computer isnt actually busted like I was beginning to suspect nor was it any of the various beta programs / haxies I may have been running. (Since all of them were gone once I did a clean install.) Maybe 10.4.7 will address it?

SMON process consume High CPU in production setup.

Hi,
Recently we migrate our storage from IBM DS4700 to IBM v7000. on last Saturday from yesterday and today cpu almost 100 percent in peak hours.
Right now our datafiles in SSD and archivelogs in SAS disk.
Please suggest
regards,
Karthi.

Hi Karthi,
Which SMON process is consuming CPU ,I mean,Database SMON /ASM SMON if is in use.
+ Install and enable OSwatcher with atleast 30 seconds interval and monitor which process /what is causing high CPU.
+ If they are oracle processes ,then validate what are they doing at database level .
Does it comes from any application code ,if so validate those sqls.
+ Install procwatcher to understand what are they doing .
Refer::-----------
==============
Procwatcher: Script to Monitor and Examine Oracle DB and Clusterware Processes (Doc ID 459694.1)
+ Then as per your environment get pstack/procstack of that process in 30 seconds interval for 3-4 times .
If try to identify the issue ,if required please open service request with us.

Airport process using 90%+ of CPU

I have a MacBook and for some reason, using the activity monitor I see Airport is using up almost one full core. I've tried rebooting and such and airport is always using a lot of CPU time. Its very annoying since all this processor usage is causing my fan in my Macbook to run at full throttle all of the time. I'm on a wireless G network with WPA.

I have a MacBook Pro and I am experiencing the same problem. After each reboot or wakeup a process called airport (probably /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/air port) takes up a lot of CPU.
I just kill the process. After a reboot, killing needs administrator rights, but then almost immediately the process starts again. Killing it again makes it go away till the next wakeup or reboot.
It seems that wakeup in the neighborhood of a WiFi base guarantees this problem. However, on the road out of reach of any base, I can usually wake up the machine without a problem.
Killing the process does not seem to interfere with correct functioning of airport in any way.
As said before: it eats away battery life and makes the machine uncomfortably hot. Apart from that, because a lot of CPU is being used by this process, it is very hard to resume your work after a wake up because the machine becomes very unresponsive.
As a temporary measurement, I launch activity monitor automatically. The amount of clicks to kill the process is then minimal. Still, it is annoying and makes me look clumpsy if I am rewaking my machine for a presentation or meeting.
