Wake-On-Lan (WOL) after sleep causes high CPU usage

Hi,
I noticed a problem with constant high CPU usage on one of my cores.
As much as 60% was used.
The problem occures after I put the system to "sleep" (S3 state) and perform a WOL with a "magic packet".
I discovered that ACPI.sys+0x1af44 thread was responsible (using sysinternals ProcessExplorer) under the System process.
If i perform WOL while the machine was shut down everything works perfectly.
My NIC is "Realtek PCIe GBE Family Controller" and I'm using the latest drivers.
I discovered that if I disabled the option in Power Management for the device: "Allow this device to wake the computer", the CPU usage immediately went to normal (without restarting). But enabling it back the high CPU usage resumes. Performing
another sleep and awaking the system with power button "resets" the CPU usage issue for "good". Until i WOL from sleep again ofcourse..
I contacted the motherboard manufacturer of the problem but so far no real answer.
I'm saddened because I need the WOL feature.
I'm hoping somebody who has more insight in the behaviour of ACPI on W7 can answer my questions.

Applet causes high CPU usage

Hallo,
I have a strange problem with my applet. It displays medical images. After loading Image the CPU usage of java jiumps to 100% on single core processors and to 50% on 2 core processors, and stays high, without any interaction of user. I've used Java VisualVM to profile the applet and it says that: javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run() 94.76343 787851 ms (94,8%) 58823 times invoked is
I'm not sure this is the cause of the problem. I don't use any loops while noone is interacting with the applet. Has anyone idea or suggestion what's going wrong?
This CPU load is independent of browser and operating system. I've profiled it on firefox.
with regards
Rafal Ziolkowski

Good job figuring it out.
Rule of thumb to prevent future problems: the paintComponent is used for painting and should do nothing else - setBorder() is a state change and thus does not belong in the paintComponent() method. You can all relate it back to a general programming rule of thumb: a function or method should perform only one task.

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

Mixer window can cause high CPU usage, crashes

This is probably one of the weirdest bugs I've seen for a while. Here are the steps that I reproduce it for me, maybe someone will want to try this out and see if they get the same.
1) Open an Empty Project template.
2) Create 16 instrument tracks when it gives you the dialog. (even 1 will be enough, but the effect is clearer the more tracks you create)
3) Open the mixer. Either in a window or in the pane.
4) Now create a "multi-timbral" instrument track with the plus button (use the checkbox there).
5) Select the 16th track, and now select one of the arrange tracks of the multi-timbral instrument.
6) Open up Activity Monitor from your Utilities folder in Finder and see how much Logic is taking up CPU. It should be significantly higher than the idle state. On my MBP it'll be around 80%.
This is not a problem in itself, because when reproducing it like this the high CPU usage goes away when you select another track and won't return if you select the multi-timbral instrument again.
However, I have sessions where this will continue happening with a multi-timbral instrument all the time. Not only that, I've had Logic crash when this starts happening. And this whole thing will slow down the UI considerably when it's active.
The workaround that seems to work for me is simply not keeping the mixer window/pane open.

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .

Adobe stuffs cause high CPU usage

I just download Creative Cloud a few days ago for Primiere CC and since then there is always something from it that causes ~50% CPU usage. I tried to end the process by Task Manager and something else just replace the previous one's place. Sometimes it's CEP Service Manager, sometimes it's Core Sync, CEF Helper, etc. and it's driving me nut! I mean like right now Firefox only takes about 20% while those things just sky rocket the CPU usage. What should I do? How do I stop this?

Since I installed CC, my laptop has been running very hot too.

NMIndexStoreSvr.exe causes high CPU usage

Within 2 - 24 hours after I restart my computer I'll notice that the CPU fan is very loud. When I open Windows Task Manager the CPU is at 95-100% usage. When I look at processes I see that the file "NMIndexStoreSvr.exe" is the biggest culprit. When I end that process, my CPU usage drops to 5% almost immediately.
Ending this process does not seem to affect Itunes. Has anyone else run across this. Is there a fix or a way to keep that file from running when I start up Windows?
Any help will be greatly appreciated.

Hi Adrian1988,

I saw your post regarding the audiodg.exe error message. I did some research into that message and as you mentioned most of it is for Windows 7, I can find very little for Windows 8. What other games do you notice this issue with? I looked into DOTA2 and it lists XP, Vista and Windows 7 under the requirements but doesn't mention Windows 8.

Persistent Active Requests causing high CPU usage and load average

Hi, we've deployed a JSP application on standalone OC4J talking to Oracle DB. The whole thing runs on Sun Solaris. On some occasions (still investigating what causes this), the number of active requests rises (as seen from EM console) and never drops down. The weird thing is, the load average numbers are proportional to the number of persistent active request. If there are 3 active requests, load avg will be [3.x 3.x 3.x], and whenever persistent active request exist, CPU usage will shoot up to over 90% (usually between 95% - 100%). When the system is running normally, CPU usage is usually less than 20%. Is it possible to track down this problem and how? Many thanks.

Welcome to Apple Discussions!!
The icons on the right of the menu bar … show a beachball when I put the cursor over themWell, if this was your only problem I would put it down to a corrupt preference or cache file. Nevertheless, it is worth seeing how much this helps.
The file you need to trash is 'systemuiserver.plist'. But there are potentially two of them, plus it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
See if this improves the situation, and post back with any remaining oddities.

BizTalk 2013 SFTP Adapter : Host Instance configured for SFTP Receive cause high CPU usage

Hi,
Our BizTalk 2013 Server test env have 16 GB RAM. We have one SFTP Receive Location which is using a dedicated Host instance for SFTP receive.
As soon as we start this SFTP Host Instance it starts consuming 50-60% CPU. (Even when it is not handling any file receive)
As suggested in below thread, to fix this issue, we changed the SFTP RL default configuration. i.e. Changed polling interval from default 0 sec to
10 minutes and also changed the RL Schedule window to business hours only.
https://connectedpawns.wordpress.com/2014/04/13/biztalk-2013-sftp-adapter-biztalk-host-receiving-throttled-because-processmemory-exceeded-the-configured-throttling-limit/#comment-2602
Even after changing the RL configuration , the Host Instance continuously consumes ~60% CPU.
Any suggestions to troubleshoot more on this issue ?
Thanks in advance !!

Flash Player Causing high CPU usage NT Kernel

Hi
I have windows 7 with Firefox 26 and noticed that the NT Kernel and system process is running my cpu at 50% - I have a dual core.
After some research and testing I have realised that it is flash causing it when a site opens like Ebay for exapmple.
If I deactivate the plugin all is fine - cpu at about 7 - 20%. Ebay etc will ask to activate the plugin and the CPU jumps.
Same thing with other flash sites. Facebook etc
No issues with the other browsers - Chrome and IE.
I have tried uninstalling flash and firefox - and then doing a clean install but not fixed.
I tried posting on the firefiox forum and they recommended to come here.
Any thoughts?

No that would be too much pain I think - copying everything across again.
No, no, no... I mean create a new admin account JUST FOR THE PURPOSE of testing the installer. It'd be a totally blank, empty account.
THAT'S the best way to determine if your account has permissions issues. If the installer and Flash Player works, as it does on your wife's account, you'll know where the trouble lies... in your account, which may or may not mean you have to move everything over. If this isn't something "liveable", then move stuff. If it IS liveable, then I wouldn't bother.

MF4700 Series driver causes high cpu usage

Hello, I just purchased a Canon MF4770 Multifunction laser printer. After installing the Linux driver my Ubuntu system reports that the driver c3pldrv is using 25% of my cpu. The computer is running hot and the fan constantly blows to cool the CPU down. Is there any fix for this?

Hi rfrye7533.
The Linux Version driver package includes code components that were not written by Canon USA or its affiliates. In addition, Linux exists in many different versions, and the driver cannot be tested against all of them.
Thus, Canon USA is not able to provide a support for this driver software. The driver is provided "AS IS". For assistance with the installation of the software, we recommend that you contact Ubuntu's technical support.
We understand, and sincerely apologize for any frustration you have experienced, but we hope that you understand our rationale.

Call Park service causing high CPU usage

Hi,
I've got a Lync 2013 pool with 4 servers running. Everything is working fine except I notice that when I enable the call park service, the CPU usage goes from hovering at around 4% to jumping all over the place (anything from 11% to 30%). I've
not seen this behaviour on any other Lync platform I have deployed.
All machines are virtuals, running 2 Sockets with 8 cores each. Each server has 25GB of RAM. Any perfmon report I run only confirm that the Call Park Service is using a lot of CPU resource (compared with other services)
Any help greatly appreciated.
Thanks
Mike

Please check if the CPU usage drops down when you stop the call park service.
Please check the Call Park Configurations are correct by articles at

I have a document created by printing an AutoCAD drawing. As soon as I place a text field (form) in the document, Acrobat freezes for about 2 minutes and Acrobat.exe more than 50% of the CPU. This happens with each text field placed.
To make things more interesting, I was doing this with Acrobat X. Rather than wait, I moved to another computer with Acrobat 9 and tried again on the same document. The same thing happened. This seems to be document related. The one page document 11x17 is206k in size.
Any ideas?

Since I installed CC, my laptop has been running very hot too.

XML select query causing very high CPU usage.

Hi All,
In our Oracle 10.2.0.4 Two node RAC we are facing very high CPU usage....and all of the top CPU consuming processes are executing this below sql...also these statements are waiting for some gc wiat events as shown below.
SELECT B.PACKET_ID FROM CM_PACKET_ALT_KEY B, CM_ALT_KEY_TYPE C, TABLE(XMLSEQUENCE ( EXTRACT (:B1 , '/AlternateKeys/AlternateKey') )) T
WHERE B.ALT_KEY_TYPE_ID = C.ALT_KEY_TYPE_ID AND C.ALT_KEY_TYPE_NAME = EXTRACTVALUE (VALUE (T), '/AlternateKey/@keyType')
AND B.ALT_KEY_VALUE = EXTRACTVALUE (VALUE (T), '/AlternateKey')
AND NVL (B.CHILD_BROKER_CODE, '6209870F57C254D6E04400306E4A78B0') =
NVL (EXTRACTVALUE (VALUE (T), '/AlternateKey/@broker'), '6209870F57C254D6E04400306E4A78B0')

Also not able to generate execution plan for this sql using explain plan- getting error(ORA-00932: inconsistent datatypes: expected - got -)
Please help me in this issue...
How can i generate execution plan?
Does this type of XML based query will cause high GC wiat events and buffer busy wait events?
How can i tune this query?
How can i find that this is the only query causing High CPU usage?
Our servers are having 64 GB RAM and 16 CPU's..

I think xml schema is created already...and its progressing as you stated above. Please correct if i am wrong.
I found all these sql from AWR report and all of these are very high resource consuming queries.
And i am really sorry if i am irritating you by asking all stupid questions related to xml.

Browser's javascript engine causing high CPU load and lost swipe events

I'm having performance issues on some websites. I think that my the javascript engine in the Playbook's javascript engine is causing high CPU usage, which means the device misses swipe gestures.
Visit: http://www.bbc.co.uk/news/world-middle-east-15814035
Once the page is loaded swipe to scroll up and down. On my device (and my friend's) it is incredibly slow. Sometimes it refuses to register any swipe events.
Now turn off javascript and reload the page. Swipe to scroll up and down. Smooth as silk!
My device is a new 16Gb with version 1.0.7.3312. Thanks

I'm having the same problem on a number of websites with my 32gb Playbook. On the same sites that I notice slow, sometimes barely responsive swipes for scrolling my wife's iPad 2 handles them with ease. Disabling javascript fixes the problem however a lot of websites including gmail requires javascript to be enabled on your browser to load. I notice the problem quite a bit when using webmail to check my gmail account which is rather frustrating because it is my only option until PB gets a native email client. My PB is running software 1.0.8.4295, but the problem was also occurring when it was running 1.0.7.
