    Svchost.exe using a lot of memory


    I have two instances of Svchost.exe running a lot of memory. One
    instance is running at over 200,000 and one running at over 100,000. I
    have been experiencing the BSOD multiple times a day due to physical
    memory dumps and I'm pretty sure this is the cause. I was wondering if
    any of you experienced users can look at the list below and tell me if
    anything stands out.

    I checked what services were running under each svchost.exe and this is
    what I found.

    200,000 services:

    wuauserv
    WinMgmt
    Themes
    ShellHWDetection
    SENS
    Seclogon
    Schedule
    RasMan
    ProfSvc
    MMCSS
    LanmanServer
    iphlpsvc
    IKEEXT
    EapHost
    Browser
    BITS
    AeLookupSvc



    100,000 services:

    wudfsvc
    WPDBusEnum
    Wlansvc
    WdiSystemHost
    UxSms
    TrkWks
    TabletInputService
    SysMain
    PcaSvc
    Netman
    EMDMgmt
    AudioEndpointBuilder

    Thanks a ton!

    200,000 and 100,000 of what unit?

    Lets's see how many instances I have running on my 64-bit desktop
    with 8 GB memory:

    svchost.exe SYSTEM 268 MB
    svchost.exe SYSTEM 16 MB
    svchost.exe NETWORK 7 MB
    svchost.exe LOCAL 8 MB
    svchost.exe LOCAL 6 MB
    svchost.exe LOCAL 5 MB
    svchost.exe NETWORK 3 MB
    svchost.exe LOCAL 200 KB
    svchost.exe SYSTEM 3 MB
    svchost.exe SYSTEM 1 MB
    svchost.exe SYSTEM 200 KB
    svchost.exe NETWORK 200 KB

    In other words, having more than one instance of svchost.exe
    running at once is normal if you're using enough system services at
    once. Many of these instances aren't shown unless you tell
    Windows Task Manager to show processes from all users.

    How much physical memory does your machine have (RAM
    only; exclude the hard drive)? I'd consider your problem a
    possible sign that you don't have enough physical memory to
    run whatever you're trying to run, and make it run properly.

    The Performance tab of Windows Task Manager has a
    button that will start the Resource Monitor if you have it
    installed, and probably let you download it it it's not already
    installed. That program is good for digging out more information
    about resource use, especially if you're able to identify which
    task to look for its resource use.

    I'm having a number of problems with Windows Mail, Windows
    Live Mail, and the backup program, but not BSODs.

    I suspect that some of my problems are due to not having
    enough information about the registry values that control the
    Vista SuperFetch feature to correct problems related to that
    feature.
