Script pending on Running status when schedule as task

Hello everyone,

I face this problem on every script, it's hard for me to find root cause, can some one help please? :-)

My script usually contains following line to load PowerCLI:

add-pssnapin VMware.VimAutomation.Core

Whenever I run it on PowerShell prompt window, it's working fine.

I created scheduled task to run the script daily, first several runs worked fine, but it's pending on load PowerCLI snapin after few days, no error, just pending there.

I tried create task by .ps1 file directly and by .bat, no help.

I tried on PowerShell 2.0 with PowerCLI 5.5 Release 1, and PowerShell 3.0 with PowerCLI 5.5 Release 2, both does not work.

It's not mentioned on PowerCLI release notes.
