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.

BTServer causing high CPU utilization

Just got a new MacBook Pro with OS X Lion and updated to 10.7.1. I've seen the BTServer process cause high CPU utilization twice now. One morning I also noticed that the fan was running loudly while the lid was closed and the computer was locked up; I had to force power it off. Anyone seeing similar issues? Doing a search for BTServer on Google or even here in the Apple Support Communities does not bring up anything related to Lion at all, only iPhone-related articles.

yup, i had this problem too. i have a new 2.2ghz macbook pro and while at a coffee shop, i noticed my battery draining very quickly, and a look at activity monitor showed that BTServer was running away with high-cpu utilization. i killed off the process and didn't notice any loss of functionality.
not sure what it was supposed to do with so much freaking cpu cycles!!!
is this for bluetooth? i dont even have bluetooth on. im not happy about this having to be something i'd need to keep a eye on when i'm trying to maximize my battery life.

How to over come jlaunch process High CPU utilization

Hi ,
I am facing problem in Poratal Production system
Jlaunch process consuming more CPu utilization, Can you suggest me How to overcome this problem with out restart server

Hi,
This is because of parameters of your J2ee engine are not optimized. Check SAP 723909 Java VM settings for J2EE 6.40/7.0 Prerequisite for performance optimization

Very high cpu utilization with mq broker

Hi all,
I see a very high cpu utilization (400% on 8 cpu server) when I connect consumers to OpenQ. It increase close to 100% for every consumer I add. Slowly, the consumer comes to a halt, as the producers are sending messages at a good rate too.

Thanks ak, for the response.
Yes, the messages are consumed in transactions. I set imq.txn.reapLimit=200 in Start Arguments in jvm configuration.
I verified that it is being set in the log.txt file for the broker:
-Dimq.autocreate.queue=false -Dimq.autocreate.topic=false -Dimq.txn.reapLimit=250
It did not make any difference. Do I need to set this property somewhere else ?
As far as upgrading MQ is concerned, I am using glassfish 2.1. And I think MQ 4.3 is packaged with it. Can you suggest a safe way to upgrade to OpenMQ 4.5 in a running environment. I can bring down the cluster temporarily. Can I just change the jar file somwhere to use MQ4.5 ?

CB21AG High CPU Utilization

We have a problem with CB21AG cards causing high CPU utilization on WinXP. Task manager shows the CPU pegged at 100%, but the individual processes don't add up to 100%. IE, there are "missing" CPU cycles. Using Process Monitor from SysInternals, we see that NDIS (Windows network wrapper) is creating numerous DPCs and causing the CPU usage. Shutting down the wireless card fixes the problem. It's an LWAPP environment (WiSM 4.0.217), with various versions of the client drivers up to ADU 3.6.
Does anyone know anything about this?

It'd be hard to say anything for certain without seeing all the test stuff ... but it sounds like old or corrupt drivers / utilities.
There are some Microsoft-side patches / updates that may be useful as well.
Try reloading the (and / or updating) the drivers & utilities. If you're using Zero Wireless Config, try (at least for experimentation) the Cisco utilities (ADU) or vice-versa. It might narrow down which specific software modules are involved.
IF you have a spare card, it might also be worth a shot ... there could be a bad software component in EPROM that's causing the problem.
I believe some of the driver/utility updates include updated firmware loads for the NIC too.
Good Luck
Scott

High CPU utilization in voice gateways

High CPU utilization during non-peak hours in all the gateways.
Process-http core is utilizing more CPU and it reaches to 99% and after sometime it automatically resolved and sometimes reload solves the issue.
We are using contact centre and back office calls.
Any reason why this is happening?
IOS version- 15.0(1)M9

Hi Tagir,
We don't have ip http server and ip http secure-server command in our gateways.
No connections for the sh ip http client connections.
Please advice what could be the cause of the issue and also note that this is happening only in the late night when there is less call volume/no calls to the gateway.
Thanks...

Desktop Window Manager high CPU utilization

I have several Windows 2012 servers that are showing high CPU utilization (70% or higher) coming from the Desktop Window Manager. I do not have the Desktop Experience feature installed on these machines. The interesting thing is that the process
for dwm.exe does not show up as a service that I can stop or restart. I've read through the various posts about re-registering dmw.exe so that the service shows up again, but nothing has worked. Since these are application and file servers with
no need for regular desktop use, I don't really need any fancy desktop graphics or performance. I have the Advanced Performance Options set to 'Background services'. Can anyone tell me how to stop dwm.exe or at least reduce it's CPU footprint?
Thanks,
Joe

Hi Joe,
Based on my research, On Windows 8 and Windows Server 2012, DWM is used at all times and cannot be disabled.
For more detailed information, please refer to this article:
Desktop Window Manager is always on:
To troubleshoot the high usage of CPU, I would like to recommend to follow this article to collect and analyse the relevant log files and dump files:
Troubleshooting High CPU performance issues - Part 1
If you want to analyse the dump file, I also recommend you can open case and contact Microsoft support.
I hope this helps.

EEM applet that triggers on high CPU utilization

Hi Folks,
I am trying to create an eem applet which triggers on high cpu utilization (detected by erm).   The applet should then tftp the output from "show proc cpu sorted" to a tftp server.
I am trying to configure this on a 1841 running 124-24.T3 code
This is my config:
resource policy
policy HighGlobalCPU global
   system
    cpu total
     critical rising 5 falling 2 interval 10
    cpu process
     critical rising 5 falling 2 interval 10
! I'm not sure whether it is correct to monitor 'cpu total' or 'cpu process'.   The rising thresholds are deliberately low to maker testing easier
event manager applet ReportHighCPU
event resource policy "HighGlobalCPU"
action 1.0 cli command "show process cpu sorted 5sec | redirect tftp://192.168.1.1/highCPU$_resource_time_sent.txt"
action 2.0 syslog priority debugging msg "high cpu event detected, output tftp sent"
The problem is that I can't seem to trigger the applet.    I have generated enough traffic to push the cpu utilization to over 30% (according to 'show proc cpu'), but the applet does not appear to trigger (no syslog messages appear, and my syslog server does not receive anything).
If anyone can tell me what I've done wrong here I would be very grateful!
Thanks,
Darragh

I am just replying off the top of my head but I believe you
need to also add to your conf the line

High CPU Utilization by J2EE engine

Dear team,
I want to find the tread causing high CPU utilization within the "jlaunch" process. As stated in SAP note: 743204. I ran the command "tps -a <pid> -a" in the development box and it it running fine. But the same command in the production portal is giving us the following error:
jueppci:/#/usr/sap/tps -a
Initialize measurement (10 sec) ...Memory fault(coredump)
I did a strings command om the core and I got
jueppci:/#strings core
libdl.so
Why is tps not running properly ?

Hello,
Thanks Russell. It is HP-UX 11.31 (11i v3). We have opened a Very High Message with SAP. SAP AG and HP are working with us to solve this issue. We will be applying some patches and doing a lot of Java parameter changes !
I'll update the solution once the system is stable and the case with SAP is closed.

3G High CPU utilization when waking

Recently gave my iPhone 3G to my wife, restored it to a new phone, then synced it with her information, music, applications, etc. She previously had used an iPod touch, and basically was trying to upgrade her to an iPhone.
The phone worked fine when I had it. I only had a short time with this specific phone as it was replaced under Apple Care about a week and a half before turning it over.
Now it pretty consistently is unresponsive when trying to wake it. By bringing up the System Activity Monitor App as soon as possible after powering it up, and leaving that app active when putting it to sleep I can see that the CPU gets slammed for a while during initial startup and has a significant period of very high CPU when waking. At this point I believe the cause of the unresponsive behavior is that the CPU is maxed out doing something.
I've compared the running processes to an iPhone 3Gs and they were identical except the 3G was missing the MobileMusicPlaye until I brought up the iPod on that phone.
There are 2 things about the initial setup of this phone for my wife that are causing me some concern;
1) When first connected to iTunes after the Factory Reset I was prompted to restore an older backup than the iPod Touch one I took right before the swap. I didn't realize it at the time and accepted that restore.
2) I was prompted to upgrade and followed through with an upgrade to 3.1.2 after the Factory Reset even though the phone was at 3.1.2 before the swap.
At this point I'm thinking about doing another Factory reset and set it up by sync only (no restore) but not looking forward to the time investment that will take.
Any ideas on where the high CPU utilization is coming from on wake? Is that a reasonable theory that the high CPU is causing it to be unresponsive when first woken up.
Any other insight from others that have been through this?

I ended up restoring the 3G phone to Factory settings and then sync'ing the desired information / applications onto it (did not restore the previous backup). The behavior is improved but this phone does seem to get bogged down when waking (observing high CPU utilization when monitoring with System Activity Monitor and experiencing sluggish / jerky response to user actions with no applications or just Mail running). The periods of non-responsiveness are not as long or as severe at this point, but still noticeable.
I'm at a loss since under the conditions I'm observing this there is nothing but Apple software running on the device (behavior is present with or without SAM showing me the CPU utilization). I'm a little suspicious that it might have something to do with re-establishing the WiFi connection, but it seems to continue for a bit after the WiFi icon appears in the status bar.
I'm probably going to make a genius appointment to see if they have any other ideas.

High CPU utilization on CSS 11501 version sg0750303

Hi everyone,
I have the problem about High CPU utilization on CSS 11501 version sg0750303.
Our customer has used one pair of CSS 11501 (active-standby).
As a matter of convenience, called "Old CSS" after here in this post.
However traffic via Old CSS had been increasing so customer decided to add one more
pair (active-standby) of CSS to separate traffic.
Yesterday we installed new two CSS 11501 version sg0750303 (active-standby).
As a matter of convenience, called "New CSS" after here in this post.
Today, active CSS 11501 and standby CSS 11501 which were installed yesterday (New CSSs)
indicates High CPU utilization.
Active CSS 11501:
Peak CPU utilization: about 85%
Average CPU Utilization: about 60%
Standby CSS 11501:
Peak CPU utilization: about 40%
Average CPU Utilization: unknown
I do not understand why CPU utilization of both New CSSs become high.
The traffic pass through New CSS less than Old CSS, because the traffic is separated into
Old CSS and New CSS.
And CSS's configuration parameters (service, content, access-list) also less than Old CSS,
because real servers are also separated into Old CSS and New CSS.
Old CSS indicated average of CPU utilization about 20% before installing New CSSs yesterday,
in spite of all traffic pass through Old CSS only.
I wrote "New CSS remains High CPU utilization", however end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I have the question "CSS 11501 sg0750303 remains High CPU utilization on normal situation ?"
And customer uses MTRG to poll SNMP for Old CSSs and New CSSs.
So I have the question "CSS 11501 sg0750303 become High CPU utilization in case of receiving
SNMP polling ?".
Or if this situation is abnormal we need to start investigation.
Would you please let me know how do we investigate this situation.
I found the DDTS CSCek57080 "Performance issue using arrowpoint-cookie with ASR".
Release note of this DDTS says that
A customer was using a CSS pair configuration where arrowpoint-cookie
is being used along with a redundant-index on many content rules. When
the flow rate increased to a few hundred flows/sec, the peer message
queue of the CSS receiving ASR related message began to fill up.
When the peer message queue became over subscribed, the CPU increased
and the CSS became unstable.
New CSSs have configured redunrant-index on two content rules, and end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I think this DDTS does not related to this case.
Your information would be greatly appreciated.
Best regards,

Gilles,
Thank you very much for your cooperation.
I got the capture you instructed us.
The following are additional information from our customer.
At time user traffic path through the active CSS, active CSS indicates;
CPU utilization always range of 30% - 40%
Peak CPU utilization about 60% - 80%
At time there is no user traffic pass through active CSS, active CSS indicates;
CPU utilization always range of 0% - 5%
Attached files are named "Active CSS.log" and "Standby CSS.log".
"Active CSS.log" is captured on active CSS and "Standby CSS.log" is captured on
standby CSS.
I found the following process is using resource by looking the output of
"shell 1 1 spyReport" command.
On active CSS,
tFlowMgrPktR 8ba24070 50 26% ( 1469) 20% ( 26)
On standby CSS,
fmPeerMsgTas 8a511510 50 16% ( 176) 10% ( 7)
Your comment would be greatly appreciated.

High CPU Utilization on ASA 5540

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. Any ideas on how I can find the root cause of the CPU high utilization?

Hi rlortiz,
I ran into this issue as well on an ASA 5540 with only about 150 users. In the case if you are using large modulus operations including large key size certificates and a higher Diffie-Hellman group, it will cause for high processing.
Since the default method of processing these operations is software-based, it will cause higher CPU usage and also slower SSL/IPsec connection establishment.
If this is the scenario for you, use hardware-based processing by using the following configuration:
"crypto engine large-mod-accel"

Airport Process utilizing high CPU utilization
