    Is this causing spoolsv.exe to grow in memory? Any workaround?
    ==================
    SELECT * FROM __InstanceCreationEvent WITHIN 1 WHERE TargetInstance ISA
    'Win32_PrintJob'
    ==================


    Finally narrow down to this -

    Why the follwing few lines of codes cause spoolsv.exe keep growing / eating
    memory? It checks Win32_PrintJob once every second and I guess that has
    something to do with spoolsv.exe. It keeps growing and eventually bring
    down
    my systems (WinServer 2003 and XP home in my case)

    How can I stop it from growing? Any best practice sample codes of doing
    this?

    Thanks

    ==========
    Imports System
    Imports System.Management
    .......

    Dim watcherPrintJob As ManagementEventWatcher
    Dim scope As New ManagementScope("root\CIMV2")
    Dim qryPrintJob As New WqlEventQuery("SELECT * FROM
    __InstanceCreationEvent WITHIN 1 WHERE TargetInstance ISA 'Win32_PrintJob'")
    watcherPrintJob = New ManagementEventWatcher(scope, qryPrintJob)
    watcherPrintJob.Start()
    scope = Nothing
    qryPrintJob = Nothing
    watcherPrintJob.Dispose()
    ===================
