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

LMS 4.2.3 Server high CPU Utilization

Hi All,
We are observing high CPU utilization on the lms server. tomcat is the process eating more than 1GB of the memory i checked from the task manager.
Server details:
device license : 100
windows server 2k8 R2, with 8gb physical memory.
anybody suggest what might be causing the issue.?? because of this performance reports were affected.
Regards,

1. Here is the query to get the pollerwise managed MIBObjects:
"select count (*), PollerName from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId = b.PollerId and b.Poller_State NOT IN (1) Group by b.PollerName;"
2. Here is the query to get the total mibobject count for the active pollers
“select count (*) from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId =
b.PollerId and b.Poller_State NOT IN (1);”
Hope it will help

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.

NSAPI plugin has high CPU utilization on Sunone web server 6.0 SP5

Hi,
I am running WL 6.1 SP3 with pluginProxy SP03 on Sunone web server 6.0SP5 on Solaris.
Seeing very high CPU utilization with 3 threads running wl_proxy (about 33% each).
Any latest NSAPI pluginproxy patch I can use to fix this?
Walter

I'm having the same problems as all the above posts. I run a colloborative tool which uses IPlanet as a directory server and I receive the Event ID:25 Source: WebServer 6.0 error as well as Event ID:0 Source:https-admnserv6.0 which gives "the local computer may not have the necessary registry information or message DLL files to display messages from a remote computer". I have 3 servers built and all exhibit the same errors.

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 ?

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

WAAS experiencing high CPU utilization

We are monitoring WAAS devices for CPU utilization in our Network.Currently we have set the threshold for 70%. At this threshold we see a large number of alerts from WAAS crossing 70% CPU utilization. I guess 70% CPU utilization is normal for WAAS. Am I right???

Hi Daniel,
Yes, during the peak hours sometimes the CPU shoots even upto 95% and then in next 5 min comes down to normal below 70%.
Since our threshold is 70%, we get a lot of inactionable(because it becomes normal in 5-10 miinutes only) alert.I was wondering if we could change the threshold.
One of the Cisco Tac Engineer replied to the above question :
That is true. It is normal to have a high CPU utilization in normal Operation as we mentioned earlier it runs on underlying Linux kernel and linux does not use Page file rather it uses Maximum RAM that it could .

SCCM 2012 Agent and high CPU utilization.

We have numerous Windows workstations and servers running with very high CPU utilization. Services are slow to start and login can take an hour. The service running with high CPU is svchost.exe, we determined that it is Windows Management Instrumentation
that is causing high CPU in svchost.exe.
If we stop or uninstall the SCCM 2012 Agent, everything calms down on the computer.
Any ideas as to way this would be?

Same issue seen on a clients and KB2617858 resolves it. I am deploying using the App model no problem with x86 and x64 hotfixes with requisite OS requirements. Is there a way to configure to only apply to those that it applies to...if that makes sense. I
ask because my B&C x64 W7Sp1 image does not require it (I have not included it) whereas other non-B&C do - what's the condition or applicability (or non-applicability) if not as listed on the KB..! If I run it one W7 machine it says it doesn't apply
and isn't already, whereas another it installs..!
http://support.microsoft.com/kb/2705357:
To apply this hotfix, you must be running one of the following operating systems:
Windows 7
Windows 7 Service Pack 1 (SP1)
Windows Server 2008 R2
Windows Server 2008 R2 Service Pack 1 (SP1)
..obviously, if a client has the issue it applies :)
Donald Rumsfeld's 'known unknowns' comes to mind here. Sorry.

High CPU utilization with javascript

Has anyone noticed how Safari 10.4.4 has high CPU utilization (e.g. >60%) when javascript is enabled, particularly for certain websites? Opening FoxNews.com and a few Wired.com pages in separate tabs sends my Powerbook fans screaming. Disabling javascript brings utilization down to under 2%.
Any suggestions on how to fix this, or do I have to live with it? I prefer not to permanently disable javascript as a number of websites I frequent depend upon it, without consuming CPU.
Thanks,
Ira

Hi,
I agree that it's a function of the javascript code itself on the webpage, and not with the browser. It's possible to even write infinite loops in Javascript which can practically hang a web browser due to the high percentage of CPU cycles being consumed. I only knowingly encountered such a site once, when I was at a customer site with my PowerBook running on battery power. I unknowingly navigated to a site which apparently had some Javascript of some other executable code, which had the result of running my battery from about 95% charge to about 60% in about 10 minutes!
The only way to avoid this is to avoid the sites that cause this kind of problem, or to disable Javascript when visiting these sites. And if possible, send a complaint to the webmaster of the site. He/she might not be aware of this problem.

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 Lync Mediation Servers -

All,
We are experiencing an issue for last couple of weeks where we are seeing very high CPU utilization on our Lync Mediation Servers (connected
directly to SIP gateway). It is resulting in a high Jitter value and so the poor call quality.
The CPU utilization is normal on mediation boxes on our other Lync hubs regardless of the number of inbound/outbound calls
but on new Lync hub, as soon as the call volume (inbound/outbound) reaches over ~10-15 calls, CPU peaks nearly 80%-90% utilization. To reduce the call volume, we have routed our outbound calls to different hub.
To resolve this we have already taken following troubleshooting actions:
Increase CPU Cores from 4 to 8 on original Mediation VM (The mediation boxes in other hubs have 4 CPU Cores and there is no issue)
Copied known good Mediation VM and replaced a mediation box on new Lync hub
Created new VM and deployed into Mediation Pool
Monitoring of HVH’s showed no resource allocation issue
No indication on Lync Logs or Monitoring reports as to the root cause of the issue
Raised this with our SIP suppliers to compare SIP configuration with all our SIPs and they came back with no differences.
Unfortunately, after all of the above actions, we have still seeing a high CPU utilization.
Can anyone suggest something which helps us to resolve this issue?
Any assistance appreciated
Cheers,
Hemat

Anti-virus exclusion list/exceptions properly configured on the affected Lync Mediation Servers? Using dynamic instead of fixed-size virtual disks? Is the host hypervisor on the official supported list (see
Windows Server Virtualization Validation Program)?
Also do check out the recently updated guide:

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.
Best regards,

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"
