Hi
Did you mean that it is Windows essential caused this problem in your system? After this app uninstalled, is everything goes fine?

Root cause for 100 % disk utilization

Hi All,
Whenever in one of the dailog instance disk utilization is showing 100% sap system is getting very slow,what is the root cause for 100% utilization .At that moment of time when I checked the CPU usage it showed 98% CPU idle. server is on Windows NT and around 13GB of RAM is always free.
We have only one drive in the apps server.Can this be the cause of 100% disk utilization?
Waiting for ur frequent responses.
Regards,
Prashant

Hi,
I have answered similar questions :
[Re: Disk Utilization 100%]
as described above, one thing that cause 100% disk utilization is that writer processes (and read process too) is concentrated only on a single disk (equivalent to single volume group or single logical volume).
we can imagine that a large number of user hitting the single disk (where datafiles exist) on the same time with a huge transaction load.
if we can manage writable datafiles in several locations (equivalent to several volume groups or several logical volumes) where several datafiles exist, writer processes (and read process too) will be distributed to that several locations, so that each location (each disk, each VG or each LV) utilization may not reach 100%.
so it is important to design writable datafiles in multiple location in different disks to prevent 100% disk utilization.
one thing should be remember is to consult with hardware and storage vendor if there is any possibilities bottleneck or I/O issue on your hardware or storage.
hope it help you.

100% Disk Utilization

Hi All,
Most of the time of of our application server is showing 100% disk utilization and due to this system performance is badly affected. Actually Apps server is having only one disk c drive and OS as well as SAP Application sits on the same disk. other apps servers are also having the same configuration of one disk.For all apps server we are using Windows NT and CI is on HPUX platform. How to resolve this issue?
Pls help
Regards,
Prashant

Hi Prashant,
The High Disk Utilisation indicate quite a few things lets discuss one by one.
1. Here i could suspect the DB time may be high and i think there would be presence of expensive sql statements, so just check in st04.
2. If you have Oracle Database then there is a chance of I/O bottleneck.
In the oracle session the I/O section is broken into subsections as
follow:
High Average Response Time per Read Request
High Average Response Time per Commit
High Average Response Time per Buffer Busy Wait
High Number of Waits for Free Buffers
High Number of Waits for Buffers being written to Disk
High Number of Space Waits for the Log Buffer
File System Response Times
So check the above mentioned part providers.
3. In the operating system monitor of the database server also we can find
the high numbers of I/O wait. This value indicates problems in I/O. So check on this.
4. And at last do monitor SM66 and if possible trace through st05 then we can
narrow down the problem why its going for Disk utilisation regularly. Try to find out the Report Name as well.
Finally analys the subsystem using external tools and still the problem is not getting solved the get in conatct with thehardware vendor of th I/O sub system.
Thank you,

When opening an XPS file, IE hangs. Task manager shows XPSViewer.exe taking 50% of CPU.

I've seen this twice now on older XP machines (sadly, some of my users DO have to run XP) so I figured I should document it, if only because the fix is so non-intuitive.
By default, XPS documents open in IE with a helper called XPSViewer.exe. You can also open them in a separate standalone viewer by installing the Microsoft XPS Essentials thing
http://www.microsoft.com/en-us/download/details.aspx?id=11816
But that doesn't work in IE, and my users needed it to.
Sometimes, users report that when they open an XPS file, the browser hangs. Checking task manager shows that XPSViewer.exe is taking up 50% of CPU cycles. Ending the process allows IE to respond, but the document is not displayed.
The first hint at a solution was from:
http://discussions.citrix.com/topic/273861-cannot-open-xps-files/
"This issue occurs because the non-administrator user account cannot access the %WINDIR%\System32 folder. By default, WPF writes the output file to the %WINDIR%\System32 folder. The %WINDIR%\System32 folder requires administrator permissions.
When the non-administrator account tries to access this folder, the WPF caching code is triggered. This code causes the screen to flicker.
In 32-bit versions of the Windows Server 2003 operating system, the output file is D3d9caps.dat. In 64-bit versions of the Windows Server 2003 operating system, the output file is D3d9caps64.dat. "
It got me thinking that maybe i could modify the rights to the file instead of applying the hotfix...
After doing that the user could open the .xps file successfully!. But after closing the xps (internet explorer uses xpsviewer.exe to display the file) the file d3d9caps.dat disappeared from the system32 folder...
The next time the .xps file was opened by the user, the d3d9caps.dat file was not created in system32 folder as one might expect, but instead in the more appropriate path "...Documents and Settings\username\Local Settings\Application Data" folder.
So in fact, all i had to do to fix this problem was deleting/renaming the d3d9caps.dat file in the system32 folder.
So all you have to do is delete (or for safety, rename) that d3d9caps.dat file and try again! Works a treat!

In the %WINDIR%\System32 folder, find d3d9caps.dat or d3d9caps64.dat
and rename it to anything. Bamn. Fixed. That easy.

Firefox begins to start but then stops before loading any screen. Profile manager/safe mode appear then disappear. Task manager shows programs briefly in CPU then they disappear. Uninstall & reload makes no difference. Any ideas please ?

When we clicked as usual on the firefox icon the egg-timer started then went off. Nothing started up.
Checking the Task Manager showed firefox.exe briefly using the CPU then it dropped off the list.
We tried to uninstall and reload from the mozilla site (http://www.mozilla-europe.org/en/firefox/). Installation seemed to work ok, but the same problem recurred when we tried to start firefox.
Did this again, this time removing bookmarks, etc. same result.
Tried to use the profile manager - the screen came up but disappeared before we could use it.
Same thing happened when we tried to start in safe mode - screen briefly appeared but then disappeared.
Tried googling in IE to solve the problem but nothing seems to apply.
Have run all security checks but no apparent bugs or problems.
Have had to abandon firefox and use another browser. How do we get it back please ?

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
See [[Server not found]] and [[Firewalls]] and http://kb.mozillazine.org/Firewalls

Task manager show process from all user

Hi All,
Need a help.
I need to enable "task manager show all show process" for all normal users(view like XP) irrespective of admin or not.
Can any one help me how to go about this through GPO. I searched a lot in net but could not found any convincing solution for this.

This is not possible. User processes are isolated from each other. Only administrators can retrieve information about processes from other users. Either make your users local admin, or tell them this is not possible.
This is because of the security design which isolates users from other processes (service processes and other users' processes)
there are many things that don't work anymore. For example, on XP it was possible to give service applications a user interface (for example for disgnostic or development purposes). From Vista onwards this is no longer possible because allowing users to
interact with service applications is a security risk.
There are many such changes, and you have to update your processes accordingly.

Reader x or xi does not load; task manager shows 750 kb memory used

I am using windows 7 home premium 64 bits, and adobe reader x or xi sometimes does not load. However, the task manager shows that AcroRd32.exe is loaded, but only using aroung 750 kb of memory.
I must restart windows, or at least close sesion and sometimes reader loads properly. Sometimes the computer must be restarted twide to adobe function.
Does anybody has an idea why this is happening?

I'm experiencing the exact same issue.
I am on Windows 7 Professional x64 SP1. I have updated Adobe Reader to latest version, and do not have other older versions of Reader installed. I have tried opening reader by itself using Run As Administrator, as well as Run as Another User, and also in XP SP3 compatibility mode. I have tried to force PDF files to be opened in a browser window by right clicking them, selecting Open With and then selecting Internet Explorer. Nothing works. I have had this issue before, and SOMETIMES it will help if I uninstall Adobe Reader and reinstall, but even after re-imaging my entire PC, this issue comes back.
As with original poster, all I get when trying to open PDF files is AcroRd32.exe showing in Task Manager and using between 700k and 1785K of memory. No matter how long I wait, nothing else happens.
This is getting very frustrating.
Seeing as I cannot load Adobe Reader at all, is there a way to disable protected mode without loading Adobe Reader (like with registry setting)?

Windows 8.1 slows way down by 100% Disk Usage whenever playing PC Games (ntoskrnl.exe System)

This issue has been going on for just a couple days. As soon as I launch any game on my PC my computer immediately slows to a crawl. It has never froze nor have I got the BSOD. I have noticed (in the task manager) that the System (ntoskrnl.exe)
sucks the life out of my Disk and it jumps to 90-100%. I have read about 50 articles about this and many people seem to have unique reasons why this happens. It has never happened before on Win7 and just started happening in Win 8.1. So things I have
tried:
Disable unnecessary windows services.
Changed Power Options and tweaked with some of the advanced settings.
Scanned for Malware (none found)
Scanned for viruses (none found)
Disabled Windows Media Center (since the problem started shortly after installing it)
Performed Deep scan for viruses in the registry (none found)
Windows Memory Diagnostics Tool (no errors found)
As I type this I am performing another virus scan and my Disk is at 99% as shown in the task manager. I assume this is because of Norton (and System) sucking up the HDDs. Like I said this happens every time during
gaming. Not sure if there is a connection between the two. That is just when I notice the issue.
So the problem at hand makes gaming (and any other application while gaming) nearly impossible. The games and programs all work just at a very slow speed. I finally asked tech support from Microsoft and they said (without letting me explain much
detail) that I had a virus and they tried to sell me anti-virus software. Anyone able to help me resolve this issue? It is "killing" me that I cannot find a resolution for this.
I will post screen shot of anything that might be of help if you need it.
Thanks

Satellite C670D-10W - Task manager shows 100% CPU usage

My brand new laptop with factory installed windows 7 and all programs by Toshiba nothing addded shows 100% processor usage in task Manager and works pretty slow. The sum of 80 odd processes shown in task manager never reaches more than 30-50 % but bottom line is always 100%.
Tried process hacker 2, shows same processes as task manager.
What can be the problem?

If you check this forum you will see that you can find many threads with the same or similar content. Many people have noticed the same after notebook purchase, especially phenomena that notebook is pretty slow. Just without panic. What you must do is to optimize preinstalled operating system.
What can be the problem?
Brand new notebook is preinstalled with original Toshiba recovery image. This recovery image contains operating system, all necessary drivers, different Toshiba specific tools and utilities and some additional software like preinstalled McAffe or Norton antivir.
Many of these tools, utilities and additional software will start with operating system and run in the background. To be honest some of them can be deactivated, some of them can be also removed from the system. By default Windows update is set to automatic so when you go online all available windows updates will be installed automatically in the background and this will happen without your knowledge. This updates installation will make your HDD pretty busy and notebook operations will be slowed down.
I recommend you to change this option and set it to Check for updates but let me choose whether to download and install.....
I hope you understand what I want to say and if you have more questions you are welcome.

My Firefox continues to stall a lot and Window Task Manager shows that Firefox is using a lot of memory (600,000k +) What can I do to make this stop stalling?

I play Farmville or on Pogo and my computer keeps giving me the hour glass and when I look on my Windows Task Manager it shows that I am using over 600,000 k of memory. When it does that I can't do anything unless I just use the power button to shut the computer down or use the task manager to "End Process". I do not like to do either of these so I usually just sit and wait for it to fix itself then later it does it all over again.
Also when I was doing defrag on the file type tab it showed two Mozilla Firefox so I am wondering if this is the issue but I only see one in the control panel.

Adobe reader 7 hangs, task manager shows it is running twice

I am using Adobe Reader 7
I have a problem, when I click on a ,pdf file it opens but it is locked, if I try to zoom or do anything else it freezes up, I check in task manager and it shows that AR is running twice, if I oen a pdf and leave it, and dont zoom or do anything else after about a 2 minutes it will work fine,
anybody know a fix for this?
I have unistalled and reinstalled tried different versions etc, but nothing works.

Yes it runs twice, if I let it go for about 2 minutes and do not touch it or try to do anything with it, it will start to work and it will only show up once in the task manager, however if I open it and try to scroll, zoom, or even close it, it will freeze completely.

When I close firefox I attempt to reopen, it wont load...looking in task manager shows it as a process, i need to, end the process to restart firefox, Why?

when I start firefox, then close it..and attempt to restart it, I get a message that its loaded....but its not...but I see it as a process in task manager.I end the process..then start firefox again...........constant problem...............windows 7 system...8gb ram g4bit

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.
