Prstat displays PROCESS/NLWP with /0 , but high USR and SYS cpu usage

I'm running prstat on Sol 10u4 sparc and see from time to time one of more processes with high user and kernel cpu usage, The process name is just displayed as " /0". What is this ?
see sample snapshot below:
PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/NLWP

18734 root 3.7 8.9 1.0 0.0 0.0 0.0 86 0.5 52 52 3K 0 grep/1

The slash number format is used to show the number of threads (light weight processes or LWP in Solaris parlance) in a given process (see the header says "PROCESS/NLWP"). I'd guess this is a race condition where prstat finds a process exists and has consumed some CPU, but when it goes to query the data on the process it's already exited so there's no process name and zero threads associated with it. For this to be true and to see this except more than every once in a blue-moon you'd have to have a system that was having processes forked at an amazing rate.
I'd also say this is a bug, but one that you might have a hard time getting an traction on.

How could i get the kernel and user cpu usage for each process

Hi all,
In order to monitor the system CPU usage, I would like write a script to gather the kernel and user CPU usage for each process, like the prstat or top does. As always missing the shortlived kernel usage, prstat or top cann't get the precise CPU usage. I checked with the dtrace syscall, proc and fbt provider, but don't get which one is useful.
Please provide your comments and suggestion.
Thanks in adv

As I've studied the "dtrace" for a while, and seems Sun gives a pretty high score on this new feature.....I do want to know whether there's some probe can work for it, like writing a "dtrace" version prstat.You can write a prstat without dtrace. Because that's just polling at specific intervals and reading some process structures from /proc. You could have dtrace fire a probe every 5 seconds and read the same thing, but it wouldn't really be using any features of dtrace. Trhying to write it "in dtrace" doesn't make much sense.
What you could do that would be harder via other methods is to fire a probe at process exit that displayed the process information including total CPU time. They could print exactly when processes exited. Doing that without dtrace would be very difficult.

High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(

High Fan Noise and 100% CPU usage by Dock

My MacBook Pro 3.06 GHz Intel Core 2 Duo running 10.6.8 just started making a constant fan noise. When I checked the Activity Monitor, it shows my Doc CPU usage as 100%, and my Percent User Usage is about 52% System 2.5% and % Idle is 47%. These numbers are when there is nothing running except Activity Monitor. When I log out and log in as another user, the high fan noise stops, and the CPU usage of the Doc is <1%. I have tried restarting my computer, Rebuilt my Permissions, Emptied the Trash, and Reset the SMC (I think I did it correctly for the MBPro, but the Power Light did not change, and nothing seemed to be any different on my computer.) I think I recently did a recent Apple Update, but I don't know how long ago that was. But it was sometime in the past few days. Does anyone have any idea about what could be going on?
Thanks,
Frank

Will be building with an MSI z87-g65 and 4770K cpu and Windows 7 Pro

I will be building a system with an MSI z87-g65 and 4770K cpu and using either an MSI 460GTX or an MSI N6970 HD (both never used VGAs).
I read this topic and how it was solved:
https://forum-en.msi.com/index.php?topic=169759.msg1241119#msg1241119
I wonder if using the "onboard" GPU in the 4770K would be simpler to load Windows 7? I did a search and didn't find posts relating to this.

The listed cards will work fine. The integrated gpu won't work better or make it easier for Win7. Just don't enable Win8 features in UEFI.

Higher than usual softirqd CPU usage

I have a machine running 2 network interfaces, both are under constant network traffic of 1 megabit/s, I wonder if that is the reason for the high (?) softirqd/0 and softirqd/1 CPU usage, I've heard from a few bug reports I found on the net that the kernel parameter nohz=off has an effect on this behavior (I haven't tried it yet, but I will the next time the system is rebooted), here is (hopefully all) relevant information about the machine:

you could say it is normal because they used only 2 hours of CPU time per 12 days of continuous 1 megabit/s load on both cards, but here is what is strange: this system is an upgrade of a server machine with dual pentium 3 katmai at 500 mhz (using chipset L440GX+), and on that machine those kernel threads have never used ANY CPU AT ALL ! (and yes, it was under the same network load) but that machine was using a couple of Intel network cards, could the network cards be the reason ?
thanks for your help

Does PCI6534 have issues with power on io's and host cpu not powered

Are there any issues with the PCI6534 when the io has power applied and one boots the host CPU?

Hello;
I couldn't understand exactly what you meant by that.
I'm assuming you are asking if you will damage the board in case the I/Os are active and the CPU is turned off. If that is the question, the answer is no, you won't damage the DAQ device.
Hope this helps.

HT204291 I can connect to the apple TV but I am not getting display only sound with my IMAC mid 2011 and MAC Air 2012 both with Mountain Lion OS

I just upgraded to Mountain Lion after purchasing Apple TV yesterday from Best Buy.
I have signed in on the same wi-fi network (comcast 30mbps)
I was able to see photos from my wifes Iphone but not my IMac or Mac Air
Both computers connect but I am only getting audio.
I updated software on Apple TV
I shut everything down and reset my router. My Mac Air 13" 2012 was able to see the desk top but not anything that I was doing and then it disconnected.
I also tested the internet speed on the Apple TV but it just told me it was finished. (no results)

WEP as a security measure is laughable nowadays. Even a kindergarten kid with a netbook can crack the password in a few minutes. Try using WPA2 if available on the device. And the Macs will be quite happy connecting with that protocol.

I just installed IO 5.01., went through the configuration process, resynced with iTunes but now I can't get the ipad out of the configuration mode. O' on PC with XP home, SP3 installed. What am I doing wrong? Is there any way I can revert back to IO 4?

The first time I synced with the ipad I did go through "restore" from iTunes. The other options on the screen were "restore from iCloud" and "new ipad".
How do I do a restore now? With the ipad attached? Everytime I connect and disconnect the ipad to the cable, even with reboot, it takes me back to the same grey iPad configuration screen. Do I need to do a hard reset?

IPod 3rd Gen 30gb wont sync with iTunes, but works fine and shows up in windows explorer

Hi, My sister-in-laws ipod classic 3rd gen ipod is being wierd. Therres a few problems. First and foremost when we plug it into her windows XP laptop and open the latest version of itunes, which we uninstalled and reinstalled the message "The software required for this ipod is not installed correctly. Please reinstall itunes to install the required software." which we allready did. I also did everything in this article http://support.apple.com/kb/TS1363?viewlocale=en_US but when i selected the usbappl file as the driver it didnt reconize it as a driver. I also ran itunes dianostics and restarted the apple mobile device service and fixed all other issues. The ipod shows up fine in the windows explorer any help is appreciated.

That is a 4th gen iPod, and it should work with a USB port (or a FireWire port).
If you have not done a standard Restore on the iPod using iTunes, you may want to do that next. The Restore button is on the iPod's Summary screen in iTunes. This will erase the iPod, re-install its software, and set it to default settings. So, if the cause is related to software (or data corruption), and there is no hardware issue, a Restore should fix it.
WARNING: The 4th gen iPod (when used on a USB port) will ask that you connect it to a USB power adapter as the last step in the Restore process. These white square power adapters originally came with this model. If you don't have an Apple USB power adapter, you will not be able to complete the Restore, and the iPod will become non-functional. So don't do it unless you have one. A third-party power adapter may or may not work for this purpose. The USB port on your computer does not work for this purpose.

After security patch 03/04/2014 OSX 10.7.5, first one, then a second, external backup drive no longer recognized. Diagnostics for the FireWire one displays brand name of unit, but Time Machine and its own app don't see it. Where do I start?

Yesterday I installed the security patch, OSX 10.7.5 to my IMac that is about 2 years old.
Today my Seagate BackupPlus for Mac will power on but is not recognized. It does not show up as a device, Time Machine says the latest backup was DELAYED, last successful at 03/04/2014 9:35 PM (yesterday) and next backup would begin when the disk was connected. An error message I did not save said basically the drive was not recognized.   I did all drive's troubleshooting steps, including installing a newer version of their app. I tried swapping USB for FireWire, changing electrical outlets, etc.
It seems a bit coincidental to have 2 drives "fail" simultaneously. Is anyone else having this issue after this security patch? What would be the approach from the Mac side? TIA for any assistance.
Please see below regarding the second drive. Is this a red herring, or does it help pinpoint where the failure might lie?
I also have a Seagate GoFlex that WAS recognized until I did the troubleshooting on the other drive. When I put it back on after testing the other drive with FireWire, it now is no longer recognized.
Diagnostics says this about that:
FireWire Bus:

Sub-units:
GoFlex Mac SBP-LUN:
Thirdly, in after one of the testing/reboot loops, the HP WiFi printer was no longer recognized, but after a few more it came back.

I have a similar problem.
Moreover, as my external drive is split in 2 for (a) regular storage // (b) time machine usage, I can see in the Finder that I can connect to the (a) regular storage part and use it normally (image 1).
And I cannot connect to the backup part in Finder , nor see it in Disk Utility, nor use it in Time Machine (although it's listed in the Time Machine preferences, image 2), as it does not connect (image 3).
Can somebody help?

No connection with Firewire but will connect and discharge with USB2.0

My 3rd generation 40gb iPod no longer appears on my desktop or iTunes window when connected via firewire. While connected, to 3 different Macs so far, it behaves as if its plugged into the AC adaper- the charging icon appears after a few minutes but will not mount.
However, when connecting with USB 2.0 the iPod mounts fine but it receives NO power, the battery discharges within 5 minutes and shuts off.
I've known about the USB 2.0 problem but never worried about it until, suddenly ( and apparently others are having this problem ) I am no longer able to mount the iPod via firewire.
I've tried resetting in all its various forms including toggeling the hold button and plugging into the AC adapter and I have thoroughly read the trouble shooting pages.
Has Apple "orphaned" firewire? Is the 3rd generation iPod doomed to 5 minute or less connection times? Is this just a glitch that an update will fix?
Thanks in advance for any advice!
Mirror Doors G4 Mac OS X (10.4.1)

Its not the cable. I have cables and other Macs all over. I've tried the other Macs and different cables plus different cables and diferent dock connectors.
Sorry, I should have mentioned that I already eliminated that possibility.
The firewire problem just started Sep 1, 2006. I'm wondering if the last iPod update that occured the last time I was mounted via firewire initiated the problem. This seems more likely than it might have becuase of other posts complaining of firewire connection problems.
Thanks for responding though!

How to display html content with image in Adobe Flash and Flex mobile project?

Hi,
I have a html content with image in it. How to display it in Adobe Flash Builder and Flex mobile project? Which control needs to be used for this?

Hello,
The only current way is to use an iFrame, or if you only need some html tags you could use the Text Layout Framework.
Here this is the iFrame approach:

If the swc do not work in Flex4 just use its ource code which works...
...it is basically based on this:
