Powershell脚本使用越来越多的内存

Question

我有一个带有while循环的powershell脚本，当它首先使用15,504kb内存启动脚本时，但看起来每次它通过while循环时内存使用量增加约100kb，它似乎永远不会下楼。

$exe  = 'C:\Program Files (x86)\MyApp\MyApp.exe'
$logOutput = 'C:\Log\Log.log'
$logdir1 = 'C:\Log'
$storage = 'ext'
$date = (Get-Date)
"{0:dd/MM/yy HH:mm:ss}  -  START"  -f $date | Out-File -filepath $logOutput -NoClobber -Append -Encoding ASCII

While ($true){
  $date = (Get-Date)
  "{0:dd/MM/yy HH:mm:ss}  -  Calling exe for D:\" -f $date | Out-File -filepath $logOutput -NoClobber -Append -Encoding ASCII
  & $exe /logdir $logdir1 /storage $storage
  Start-Sleep -s 5

  $date = (Get-Date)
  "{0:dd/MM/yy HH:mm:ss}  -  Calling exe for E:\" -f $date | Out-File -filepath $logOutput -NoClobber -Append -Encoding ASCII
  & $exe /logdir $logdir1 /storage $storage
  Start-Sleep -s 10
}

我的剧本有问题吗？
