SVCHost.exe

svchost.exe, is consuming 200-600mb of memory on start up and does not stop until i kill the process then does it again x2, then the display settings go from the sleek design to a windows 98 look then svchost.exe stops leaking but
why is svchost.exe leaking in the first place after not doing it for 2-3 years of owning this computer running the same os.
os: Windows 7 64 bit - fully up-to-date
thanks in advance

Hi Huzaifa,
Please make sure the svchost.exe file is located in the folder C:\Windows\System32. In other cases, svchost.exe is a virus, spyware, trojan or worm. Also check the user name of the process, it should be SYSTEM、LOCAL
SERVICE or NETWORK SERVICE.
This process manages system services that run from dynamic link libraries (files with extension .dll). Examples for such system services are: "Automatic Updates", "Windows Firewall", "Plug and Play", "Fax Service",
"Windows Themes".
First you need to know what service/dll sys is running by SVCHOST.exe.
Download Process Explorer from this website

Open Process Explorer and find the problem SVCHOST.exe and check which service is taking resources.

Memory leaks- high memory usage svchost.exe

hello!
im having a kind of a similar problem. Im using a Q6600 with 4Gb of RAM running on Windows 7 x64. My physical memory usage history is 1.75GB idle but my CPU usage looks good ~ 0%.
In Windows Task Manager when i arranged the memory column, the process with the highest memory usge is svchost.exe with 116,572K. And i have 14 svchost.exe in my computer! I opened process exporer and check the legitimate of all those svchost.exe
and they are all legit. When i look at the properties of the highest svchost.exe in process explorer, the services which is running under it is as follows
AudioEndPointBuilder c:\Windows\System32\Audiosrv.dll
CscService c:\Windows\System32\cscsvc.dll
hidserv c:\Windows\System32\hidserv.dll
Netman c:\Windows\System32\netman.dll
PcaSvc c:\Windows\System32\pcasvc.dll
SysMain c:\Windows\System32\sysmail.dll
TrkWks c:\Windows\System32\trkwks.dll
UxSms c:\Windows\System32\uxsms.dll
wudfsvc c:\Windows\System32\WUDFSvc.dll
All are legit DLLS.
Is it normal to have 14 svchost.exe running at the same time(system, local service, network service in Task Manager)
and how can i reduce the memory usage of the svchost.exe?

Hi,
There can be multiple instances of Svchost.exe running at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can
be run depending on how and where Svchost.exe is started.
If you would like to reduce the usage of this service, I could share the following article with you:

Hope it helps.

Having problem with svchost.exe/ntdll.dll errors causing GPSVC (Group Policy Client) to crash preventing users from logging into the server.

Recently (within the past 2 weeks) I have noticed a few of our servers will have problems with the svchost.exe application causing the GPSVC (Group Policy Client) to crash. The only fix at that point is to reboot the server since the GPSVC service is tied
to svchost.exe and therefore is protected from being manually restarted.
I noticed the following errors when this occurs:

I've searched and cannot seem to find any information as to what may be causing this, or even really where to start. Would someone be able to help me identify what might be causing this event, specific with the Exception code: 0xc0000024, which causes
the Group Policy Client service to stop?

You still out there looking at things? If so I have an update. The issue hasn't stopped, even though it did seemingly die down for awhile, however, it is now back with a vengeance.
I am able to force it to happen by killing the svchost process that is hosting GPSVC. If I run gpupdate /force, then logout/login it does get GPSVC running again. Furthermore, if I simply start svchost again via the Task Manager GPSVC starts running again.
When I access the server remotely with KVM it acts just like it does as if I'm logging into it via Citrix/RDP which for Admin IDs gives an error saying "Failed to connect to a windows service. Windows could not connect to the Group Policy Client service...",
however, normal user accounts just get a message when logging into the server "The Group Policy Client Service Failed the Logon. Access is denied."
I haven't opened a case with Microsoft yet, but we about ready to because of the increase in these errors.
If you have any further suggestions that would be great, otherwise I'll provide an update once I get word back from Microsoft.
**EDIT -- apparently I mistook the the server's SCM's actions as my own. I was able to successfully crash the GPSVC service by killing the hosting svchost process, however, after I crashed it and let it sit crashed for awhile when I attempted
to restart either by starting a svchost task, or running gpupdate /force it failed. Either that, or there is a timing issue where if we don't restart the svchost process, or run gpupdate /force quickly enough it won't be able to recover without a reboot.

'svchost.exe has encountered a problem and needs to close.'

I keep getting this error message svhost has encountered a problem and needs to close. I am running Windows XP 3, Does HP have a solution for XP-3?

Hi,
the error "svchost.exe" that you get is not necessarily because of your printer. i advice you to scan your computer for any kind of virus or trojan, or trt the following steps:
Method 1Leave the svchost.exe - Error dialog box open, and then follow these steps.Step1: Check whether settings for the Automatic Updates service and for the Background Intelligent Transfer Service (BITS) are correctTo do this, follow these steps:
Click Start, point to Run, type services.msc, and then click OK.
In the details pane, locate and double-click Automatic Updates.
Click the Log On tab.
Make sure that the Local System account option is selected and that the Allow service to interact with desktop check box is cleared.
Make sure that this service has been enabled in the Hardware Profile list. If this service has not been enabled, click Enable to enable the service.
Click the General tab, and make sure that the Automatic option is selected in the Startup Type list. Under Service status, click Start to start the service if it is not already running.
Repeat steps 2 through 6 for Background Intelligent Transfer Service (BITS).
Step 2: Reregister Windows Update componentsTo do this, follow these steps:
Click Start, click Run, type REGSVR32 WUAPI.DLL, and then press ENTER.
When you receive the "DllRegisterServer in WUAPI.DLL succeeded" message, click OK.
Type the following commands in the Open box, one after the other, and then press ENTER after each command:
REGSVR32 WUAUENG.DLL

REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL
Step 3: Rename the Windows Update temporary folderThe temporary folder of Windows Update may be corrupted. In this case, you can rename the temporary folder of Windows Update. To do this, follow these steps:
Click Start, click Run, type cmd, and then press ENTER.
At the command prompt, type net stop Wuauserv, and then press ENTER.
Click Start, click Run, type %windir%, and then press ENTER.
In the folder that opens, locate and rename the SoftwareDistribution folder to SDold.
At the command prompt, type net start Wuauserv, and then press ENTER to start the Automatic Updates service.

Svchost.exe termsvcs eating up memory ?

Hi,
On a windows 2012 remote desktop session host I see the svchost.exe (termsvcs) using approx 13 GB of 16 GB available memory .... (Free memory on the host is zero now :-( ).
these are the memory figures:
In use: 16176 MB
Standby: 150 MB
Free: 0-40 MB
what is causing termsvcs process to take so much memory ?

Hi,
Are there many RDP sessions on the server?
You can use command Query Session to query RDP sessions.

Svchost.exe with "Dhcp, eventlog, lmhosts" services is generating thousands of page faults and I/O reads per second?

On one of our Windows 2008 R2 Enterprise (SP1) servers, we're noticing a strange phenomenon.....that the svchost.exe that hosts "Dhcp, eventlog, lmhosts" is constantly generating page faults....a few thousand per second, accumulating to billions of total
page faults. I/O reads and I/O other are also rising every second. Cpu is consistently 2%, and memory is constant. (~40M).
I'm guessing that it's the eventlog service because our HP openview log reader (opcle.exe) is also working hard to keep up. I've searched for others posting a similar problem but am coming up empty handed.
This is a MS Analysis Services 2008 server, but we haven't noticed any problems coming from SSAS. We have other file sharing-related jobs that interact with this server, that sometimes take 30 min and sometimes 6 hours, for the same workload....and
we're thinking that the 6 hour runs are somehow related to this process's unusual page faults.
Anyone else seen this eventlog strange behavior?
Thanks

How to stop svchost.exe to connect to internet?

I used a software known as TCPview. I used it to monitor what are the services that are connected to the internet. In this I found out that svchost.exe is always downloading something. It is not the automatic windows update since I changed the windows
update to manual. So please help me since my internet speed is very slow & in that svchost.exe is always downloading something....

On a newly setup system svchost.exe is the process that runs a lot of services. This means that some service may be downloading something that is important to it. Or it may always be a different service.
The resmon.exe can tell you more about which service is downloading stuff. Under network you can look for the PID of the svchost.exe that is downloading and then go to the services tab in the task manager. There you look for the PID again and hopefully find
a useful description that let's you decide what to do.
On the other hand svchost.exe is a very loved name by some shady programmers looking for new bots for their networks or for some useful login or credit card data. Meaning is all of your software and especially your windows up to date and have you an always
watching and updated anti virus software installed? Even if so a virus might be something to consider

Expected actions of svchost.exe - what is interesting, in the context of monitoring what svchost.exe is doing?

Hi,
I have seen numerous articles explaining svchost, and I think I have a reasonable grasp of it (although basic). My favourite article so far is
http://www.bleepingcomputer.com/tutorials/list-services-running-under-svchostexe-process/#advanced, which I think is well written and very handy indeed!
My current issue is that I am tweaking a security program called McAfee Host IPS, currently running on 2003 R2 and 2008 R2 servers, and getting a lot of events associated with svchost.exe that I believe require exceptions to be configured. What I do
not want to do, however, is configure an exception that hides something that may be useful information, however there is a balance required in what I am doing.
Focusing on my current task at hand, I can confirm I have seen a large number of events associated with the below. The below is all of the information I have on the Host IPS signature in question, although I am currently digging further.
IPS Signature Name: CMD Tool Access by a Network Aware Application
IPS Signature details: This event indicates an attempt by a networked application to access, modify or execute a system program that may be used to modify the configuration of your system.
IPS Signature severity: Low
I have seen a large number of events with threat source process = C:\WINNT\SYSTEM32\SVCHOST.EXE, and the following files, either accessed or executed.
C:\WINNT\System32\tasklist.exe
C:\WINNT\System32\ipconfig.exe
C:\WINNT\System32\cmd.exe
C:\WINNT\System32\route.exe
As the above reference lists DLLs specifically, and not EXEs, I am not sure if this is expected (but am gathering it is, especially as the IPS signature details refers to 'system programs').
I am suspecting that my best action here is to configure an exception for threat source process <systemdir>\SVCHOST.EXE and target files <systemdir>\*.*, as my hypothesis is that even if I have not seen it in the tuning phase, there are
a lot of similar benign actions that could potentially trigger in the day to day workings of the OS. I am also assuming that I will see similar in later versions of Windows Server OS.
To throw a slight curveball, we are also integrated with a SIEM solution. As this signature severity is low, it is mapped to a log action so nothing will actually be stopped, but if there are no exceptions, relevant events would go through to SIEM.
They could be filtered there, but potentially used in correlation rules or troubleshooting, but that obviously takes more space in the McAfee (ePO) database and the SIEM solution, which needs to be taken into account.
Thoughts on this would be greatly appreciated - I genuinely wish I knew more about this subject!
Cheers,
Darren

Hi,
I am not sure what specific information you are looking for - could you clarify? I think I have covered the majority of what is happening in my initial post, however if there is a specific bit of information you are after, let me know.
The above is an article I had stumbled across, with the majority of the information contained in the link included in my initial post. The final paragraph under 'could this process be a virus' is interesting - I have copied it below - from your perspective
is this merely anecdotal or is there something behind it (references, if they exist, would be fantastic)?
"As long as you make sure that the location of the file is in your Windows\System32 directory, you aren’t dealing with a virus. There have been cases of certain viruses trying to mimic the same filename, but they are always located in another directory."

Windows Server 2008 X64 - gpupdate takes 10min - svchost.exe (gpsvc) pid logs 8.5 million events in procmon

Hello,
We've seen that on our 2008 x64 servers the svchost.exe that holds gpsvc in it takes up alot of CPU-time. Upon further investigation I saw that when it refreshes policies it holds 1 core for 10 minutes. I setup a procmon and filtered it on the pid off the gpsvc-svchost and saw that it logged 8.5 million events.
It keeps looping events where it seems to be checking history-data under "C:\ProgramData\Microsoft\Group Policy\History\<GUIDS>".
We are using GPPreferences. Has anyone seen anything like this before?
I have the .PML-file from procmon, however its 350MB zipped so I dont know how to attach it to case.

Hi,
To better understand the issue, please help confirm the following:
1.    Do all computers encounter this issue?
2.    When did this issue begin to occur? Did it coincide with any events, such as the installation of some software?
Meanwhile, please perform the steps below to see if the issue goes away:
1.    Delete the contents in the "C:\ProgramData\Microsoft\Group Policy\History\" folder.
2.    Please perform a clean boot on the server:
1)    Click Start, type msconfig in the Start Search box, and then press ENTER.
2)    On the General tab, click Selective Startup.
3)    Under Selective Startup, click to clear the Load Startup Items check box.
4)    Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.
5)    Click OK.
6)    When you are prompted, click Restart.
If the issue continues, please help collect the following information for further research:
1.    Enable gpsvc.log:
Please create the following key in Registry Editor:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Diagnostics
Type: DWORD
Value: GPSvcDebugLevel
Data: 0x30002 (hexadecimal)
2.    Please run gpupdate /force to reproduce the issue and then collect MPSReport on the server:
1) Download the MPSReport from the website below:
http://www.microsoft.com/downloads/details.aspx?FamilyID=CEBF3C7C-7CA5-408F-88B7-F9C79B7306C0&displaylang=en
2) Double-click the executable to launch the report gathering tool on the computer.
3) Follow the steps as guided by the Wizard.
4) On the Select the diagnostics you want to run page, select General, Internet and Networking, Business Networks, and Server Components.
3.    After that, please zip the gpsvc.log (%windir%\debug\usermode\gpsvc.log), MPSReport and the PML.file and upload to the following space:

Svchost.exe errors after installing iTunes 7.0.1.8

I have two computers that starting throwing svchost.exe errors immediately after installing iTunes 7. First it happened on my desktop. In preparation to reinstall Windows XP on my desktop, I prepared my laptop to use while my desktop was out of commision. I installed iTunes 7 and immediately I started getting svchost.exe errors. I don't have the blaster worm on either machine (already checked). My desktop is behind three firewals, runs Norton, and I already did a full virus scan on both.
This is causing significant problems as my computer can't see the network, outlook can wig out, and in general my machine is unpredicatable. I hate to think that installing iTunes 7.0 leads to the need to reinstall Windows. If anyone has any ideas I would appreciate any help.

I changed my "Startup Type" for "Terminal Services" from "Disabled" to "Manual". Resolved issue.

Windows Server 2008 R2 - When svchost.exe memory-leaks Outlook does not load properly

Hi all,
We have a server which runs Windows Server 2008 R2, fully updated, and acts as a Terminal Server (Citrix XenApp 6.5).
In the past couple months we have had problems with svchost.exe leaking memory, growing to 2-3GB of RAM usage. Sometimes is occurs with weeks between the incidents, sometimes days. To solve the issue we have to reboot the server.
When this occurs, Outlook (fully updated) doesn't start for any users at all. Outlook doesn't continue from the "Loading profile.."-stage. The users who already has Outlook started doesn't have any problems, unless they close Outlook ;) .
The svchost.exe is the one which runs the services:
NSI
WinHttpAutoProxySvc
W32Time
Netprofm
FontCache
EventSystem
We've patched the server with KB2847346 but with no result. Patch KB2950358 is not applicable..
Any ideas?

svchost is hosting multiple services. when the issue occurs you can use sysinternals procmon (or enable the command line column in task manager process tab) to view to determine which service is using that much memory.
MCP/MCSA/MCTS/MCITP
Did you read my whole post, or did you just misunderstand the part were I wrote:
The svchost.exe is the one which runs the services:
NSI
WinHttpAutoProxySvc
W32Time
Netprofm
FontCache
EventSystem"
I know that svchost.exe runs ALOT of services, so when the problem occurred I checked which services the specific svchost.exe runs. Everytime it happens the svchost.exe (which leaks and has 2-3GB mem usage) runs this specific services.

SVCHOST.EXE Overflow and WMI Crash

Hello, collegues!
I faced with a problem after deploying SCCM 2012 Agent and SCEP 2012 on clients on Windows 7 SP1.
The WMI Compent crushes and svchost.exe proccess for netsvc services got overflowed and it uses a lot of RAM Memory and grows and grows.
I found out that this error appears when the agent tries to ask WMI and recieves an error ".....WBEM_E_NOT_FOUND....."
Also i found some hotfixes from MS how to solve this problem, here they are:
KB2492536
KB2465990
KB2492536
KB982293
KB974930
Anyway, these help only before installing SCCM 2012 agent, afterwards i need to rebuild WMI Repository for system working correct. By the way there is no log information in Event Viewer, provided by system. I found this error only in log files of SCCM agent
located localy in the System.
Did anyone faced with this issue?
Is there any normal solves provided by MS or maybe is it known?

Since no one has answer this post, I recommend opening a support case with CSS as they can work with you to solve this problem.

IPod generates a svchost.exe error and blocks the computer

Ok, I got an iPod Nano 2GB Silver today and when I plug it in the USB port, a svchost.exe error pops up. The only thing I can do is to press OK, but when I do that, another and another and another... same error pops up. I have to reset the computer in order for the computer to start functioning normally.
I will try to translate what the Event Viewer says about the error (and this is what the error pop-up also states):
Opening application: svchost.exe - Program error : Instructions on »0x00000000« reffered to the memory on »0x00000000«. The memory couldn't be written.
The thing is though, it's working fine on some other laptop, but I don't understand why this is happening on my desktop?! And some of the older mp3 players (not iPods) are working just fine.
Please, help me!

I have a similar problem which began a couple weeks ago. Same svchost.exe closure, only I couldn't figure out what was causing the problem. Did the format C: and clean XP install, then gradually reinstalled software. When I got around to installing iTunes again, and about 24 hours goes by, I get the same message again. Both the popup and event viewer tell me that the iPod
Service caused the failure. Windows would only suggest that the problem was caused by Windows Update.
Before the fault bucket was generated, there was an Application Information message that states:
The description for Event ID ( 0 ) in Source ( iPod Service ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Service started.
So now I am unable to keep my iPod updated, charged, used. Is this what I paid a premium price for?

Svchost.exe is accessing jp2iexp.dll hunderds of times per second

I'm running Vista 64 and was trying to get rid of all the HD IO. So I ran sysinternals Process monitor and kicked the searchindexer.exe. But I also found that svchost.exe is accessing ...\jre6\bin\jp2iexp.dll hunderds of times per second. What is it doing? My JRE is 1.6.0_12-b04.

No. I have IE7, FF3, Safari4 and Chrome1 on my system and used them alternating for testing. In this case I indeed used IE to start process monitor.
Are you suggesting that the svchost.exe is IE and it is reading the DLL? Question then still remains: why?No, certainly not.
svchost is a required Windows process.
I am guessing from the naming of the dll p2iexp.dll
^^ xp or vista
^^ ie; internet explorer
^^ p2; dunno, maybe plugin version 2 ?A quick Google ( [svchost.exe|http://www.google.com/search?q=svchost.exe] )
gives a number of b0rked entries :-(
and a number of what seems to be useful entries;

2008 R2 - Memory Leak from svchost.exe - Module "rpcrt4" is the culprit

Hi All
Over the past week or so (after a set of Windows updates and restart) svchost.exe has increasingly used more and more memory. It probably gobbles up an extra 1GB per day and doesn't relent.
After running various diagnostics, the debug diagnostic tool finally provided me this information after a memory leak test:
rpcrt4.dll is responsible for 1.76 GBytes worth of outstanding allocations. The following are the top 2 memory consuming functions:
rpcrt4!AllocWrapper+2b: 1.76 GBytes worth of outstanding allocations.
rpcrt4!Ndr64ClientInitialize+964: 1.36 MBytes worth of outstanding allocations.

I'm running 2008 R2 64bit with anywhere up to 80/100 simultaneous RDP connections at any one time.
Can anyone help or advise as I cannot find any hotfixes for this issue.
Thanks

Hi Ryan,
Please narrow it down to the specific service that is having the issue. That way you will know where to focus on.
For the specific svchost.exe that is showing the large memory usage, use task manager/process explorer/etc. to determine which service(s) are running within it. If there are multiple services running within it, I recommend you isolate them and then
restart your server. For example, say you determined that the following services are running in the "problem" svchost.exe: AudioEndpointBuilder, Netman, TrkWks, UmRdpService, Uxsms. You would open an admin command prompt and enter the following
commands:
sc config AudioEndpointBuilder type= own
sc config Netman type= own
sc config TrkWks type= own
sc config UmRdpService type= own
sc config Uxsms type= own
After entering the above commands you would restart your server for the changes to take effect. Over time you would monitor memory usage of the suspect services, and eventually it will become apparent which one is using too much memory.
Thanks.
