在 PowerShell 中运行 dotMemory 会导致“无法附加到进程”

Question

我正在尝试从命令行自动运行 dotMemory.exe 来分析多个进程。 我使用 dotMemory 独立命令行版本。

我现在遇到了有时会发生的问题。

dotMemory.exe 失败，并显示““无法附加到进程 #mynumber：确保它存在并且它是 .NET Framework 4.0+/.NET Core 3.0+/.NET 5+ 进程。””

如果我启动一个新的PowerShell实例，它工作正常，但原始的PowerShell实例无法再使用。跑多少次都没关系。我必须关闭 powershell 窗口并打开一个新窗口，它才能再次工作。

我使用的命令：

.\dotMemory-2024.1.1.exe --log-level=trace attach 14768

（14768是PID）

我也在 powershell 脚本中尝试过，但这导致了同样的问题。

$proc = New-Object System.Diagnostics.Process

$proc.StartInfo.FileName = "dotMemory-2024.1.1.exe"
$proc.StartInfo.Arguments = "--log-level=trace attach 14768"
$proc.StartInfo.UseShellExecute = $false
$proc.StartInfo.RedirectStandardInput = $true
$proc.Start()

我在 %Temp% \JetLogs\JetBrainsLog.JetBrains.2024-04-23T12-20-58.dotMemory-2024_1_1#14768.log 中找到的内容

我在日志中看到的是“Framework64 4.0.30319”。我知道 dotMemory 需要 4.7.2。是否使用了错误的 .NET 版本？

Answer 1

我找到了真正的问题。该应用程序作为服务运行。需要以管理员身份运行 dotMemory 才能附加。
