Question

我有一个脚本，用于启动作业和管理它们。我过去曾经成功使用过它，但是最近一个foreach循环将挂起。该脚本显示其进度以及已创建的线程（作业）数。脚本挂起后，我可以在任务管理器（进程浏览器）中看到正在运行的任务。当我结束在脚本下创建的最新Powershell任务时，该脚本将继续。我尝试使用多个作业脚本，但得到的结果相同。我从来没有失败过，所以没有任何日志可看。

它挂在“开始作业”上。根据我运行的子脚本，创建的作业总数多达1600个，少则60个，并且它会以随机迭代的形式挂起，直到终止该进程为止。挂。

$ScriptFile = $(".\DesMime2.ps1")
$MaxThreads = 20
$SleepTimer = 100
$MaxWaitAtEnd = 600
$filename = ".\Install3.csv"

$computers = (get-adcomputer -filter *).name
$Complete = Get-date


"Killing existing jobs . . ."
Get-Job | Remove-Job -Force
"Done."

clear-host

$i = 0

ForEach ($Computer in $Computers){
    While ($(Get-Job -state running).count -ge $MaxThreads){
        Write-Progress  -Activity "Creating Server List" `
        -Status "Waiting for threads to close" `
        -CurrentOperation "$i threads created - $($(Get-Job -state running).count) threads open" `
        -PercentComplete ($i / $Computers.count * 100)
        Start-Sleep -Milliseconds $SleepTimer
    }

    $i++
    Start-Job -FilePath $ScriptFile -ArgumentList $Computer -Name $Computer #| Out-Null
    Write-Progress -Activity "Server List" `
    -Status "Starting Threads" `
    -CurrentOperation "$i threads created - $($(Get-Job -state running).count) threads open" `
    -PercentComplete ($i / $Computers.count * 100)
}

While ($(Get-Job -State Running).count -gt 0){
    $ComputersStillRunning = ""
    ForEach ($System  in $(Get-Job -state running)){$ComputersStillRunning += ", $($System.name)"}
    $ComputersStillRunning = $ComputersStillRunning.Substring(2)
    Write-Progress -Activity "List" `
    -Status "$($(Get-Job -State Running).count) threads remaining" `
    -CurrentOperation "$ComputersStillRunning" `
    -PercentComplete ($(Get-Job -State Completed).count / $(Get-Job).count * 100)
    If ($(New-TimeSpan $Complete $(Get-Date)).totalseconds -ge $MaxWaitAtEnd){"Killing all jobs still running . . .";Get-Job -State Running | Remove-Job -Force}
    Start-Sleep -Milliseconds $SleepTimer
}

"Reading all jobs"

Get-Job | Receive-Job | Select-Object * -ExcludeProperty RunspaceId,PSComputerName,PSShowComputerName | export-csv $filename -notype

开始作业时Powershell脚本会随机挂起
