High CPU Utilization by JAVAW.EXE

Our report server is a Compaq Proliant 2 900MHz CPUs and 1 GB memory running Windows2000 SP4. Database 9.2.0.1 and iAS 9.0.2.0.1. When we are running 3 or 4 reports concurrently, we notice the CPU will spike to 100% and with that the processing time increases terribly. The process that's chewing up the CPU is JAVAW.EXE.
Anybody has seen this before? Appreciate your feedback.
Customer is also using firewall called prism.

Seen a simliar issue on another application.. just out of curiousity are you running McAfee v8 Virus scanner or equiv??... try to disable this and see if the problem goes away... if it does then it may be the vbscript/jsscript checking module causing the issue...
Worth a look??. let me know??

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.

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 Usage by System.exe (20-60%) only when system is idle

When I leave my computer idle (for 60 seconds or longer usually) the System.exe process begins consuming all of the CPU resources. I ran xperf but am having trouble finding the root cause of this CPU spike. This problem is only present since installing Windows

High CPU usage for tcc.exe on Windows XP

We have the following setup which hosts a JAVA client application:
A Netra T12 which is used as a GUI server + SGD server.
A 490 acting as another GUI server.
Internet Explorer 6 on Windows XP SP1 for the SGD client sessions.
When we run clients via this setup, we run into an issue where tcc suddenly starts eating up 50 - 99% cpu causing the clients to slow down.
Has anyone else experienced this issue? I can share configuration info but any help would be appreciated.

High CPU utilization is mostly due to queries or the background activity performed by Oracle.
Submit your statsapck report to www.statspackanalyzer.com and get the report in understandable format. Then you know where to look into.

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.

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

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

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 .

Mohit

High cpu utilization

While running weblogic managed server as windows service its cpu utilization of beasvc.exe file is fluctuating between 70% to 90%. so that my application was very slow. But this happens during peak times. Other than peak times it will fluctuate between 30% to 60%. We are using windows server 2000 OS. Can any one please suggest me in this regards.

You need to provide more details.
What version of WL? What JDK? How much memory? How many users / transactions?

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.
