PowerShell远程调用神秘地挂起(PowerShell remote invocation mysteriously hangs)

 我已经创建了一系列基本上收集有关站点的所有IIS配置的函数，当在本地服务器上运行它没有问题时执行（虽然很慢）但是当我在PowerShell 2中使用invoke-command远程运行它时它会运行并且神秘地停止大约15-20秒进入该过程。 它通常会在同一个请求中停止，但并非总是如此。 在本地执行的相同命令没有任何问题。 没有例外，它只是无限期挂起。 
 
 我可以在必要时发布代码，但它是几百行，所以我更关注如何调查这样的问题，或者是否有人遇到过类似的问题。

 有时它会达到15左右。 我尝试从我的笔记本电脑和从一台服务器到另一台服务器，行为是一样的。 
 
 这是挂起的循环：

$numanalyzed = 0
if ($true) #skip to test

foreach ($folder in $folders)

    $iis7vwebfolderpath = $folder.FullName.Replace($iis7webapp.PhysicalPath, $iis7VDirWebApppath)

    $iis7VWebDirConfigItem = Get-LNOSIIS7ConfigForPSPath -PSPath $iis7vwebfolderpath

    # add new item to list
    $iis7VWebDirConfig += $iis7VWebDirConfigItem

 函数我遇到了性能问题，我有一个单独的问题，但这篇文章有该函数的源代码： 
 
 Web管理与WMI查询Web目录属性性能问题 

I have created a series of functions that basically collect all the IIS configurations about a site, when run on a server locally it executes without issue (albeit slowly) however when I run them remotely using an invoke-command in PowerShell 2 it runs through and mysteriously stops approximately 15-20 seconds into the process. It generally stalls on the same request but not always. The same commands executed locally work without any issues. No exception is raised, it just hangs indefinitely.
 
I can post the code if necessary however it is several hundred lines so I'm more looking for guidance on how to investigate a problem like this or if anyone has encountered something similar.

Sometimes it makes it to 15 or so. I tried from my laptop and from one server to another and the behavior is the same.
 
Here is the loop which is hanging:
 
$start = [System.DateTime]::Now
$numanalyzed = 0
if ($true) #skip to test
{
# loop through all physical folders as it is much faster
foreach ($folder in $folders)
{

    write-host $numanalyzed $folder.fullname
    #figure out the virtual path to the folder
    $iis7vwebfolderpath = $folder.FullName.Replace($iis7webapp.PhysicalPath, $iis7VDirWebApppath)
    #Get-item $iis7vwebfolderpath | gm
    $iis7VWebDirConfigItem = Get-LNOSIIS7ConfigForPSPath -PSPath $iis7vwebfolderpath

    # add new item to list
    $iis7VWebDirConfig += $iis7VWebDirConfigItem

    # increment counter and report out progress every 10
    $numAnalyzed++
    if ($numanalyzed % 10 -eq 0) 
    {

       $end = [System.DateTime]::Now
       $timeSoFar = (NEW-TIMESPAN –Start $Start –End $End).TotalSeconds
       $timeremaining = ($folders.Count - $numAnalyzed) * ($timeSoFar / $numanalyzed)
       "Analyzed {0} so far... took {1} seconds, remaining time {2} seconds" -f $numanalyzed,$timeSoFar,$timeremaining  | write-host 
       "Current Folder: {0}" -f $folder.FullName | Write-Host
    }
}
}



$end = [System.DateTime]::Now
"Processed web dirs: {0} took {1} seconds" -f $iis7VWebDirConfig.Count,(NEW-TIMESPAN –Start $Start –End $End).TotalSeconds | write-host   | Write-Host
 
The function I'm having performance problems with and I've got a separate question about but this post has the source code for the function:
