Attempting to move to Windows Server 2012 with Oputils 8 and it hangs up on SPM import and will only import a limited about of devices, it hangs nmap,exe  and conhost.exe (command prompts)on the server that cannot be killed and the server has to be rebooted.   Anyone else having issues with this?  Attempted to move to version 12 but they have not incorporated imports in SPM and IPAM and missing Tree Hierarchy in IPAM....

I attempted to load 70000 and ran into similar issues...
