a VM machine got stuck

Hi,

In a linked clone pool a maching is stuck. I cannot refresh or delete the machine from the View Console. I cannot even power off the machine in Vsphere. The Power off error is "Another task is already in progress"

I guess View tries to remedy the VM too. How can I stop the View task for this machine or pool so that I can power off the VM in Vsphere and delete it from disk. I guess after I have deleted the VM, View Composer will auto create it again.

Thanks,

Edy
