We're running into issues with slow multicast performance with ZCM 11SP2.

I've spent considerable time troubleshooting the network side of things, so I'm fairly certain our network is configured correctly for multicast imaging.

However, I've recently discovered that as soon as the multicast imaging process starts the "novell-pbserv.exe" process on our ZCM server goes to very high utilization (between 90-100%). This process's high utilization also impacts server performance so it doesn't seem normal to me. I believe this is also what's causing our slow multicast imaging performance as well.

Our ZCM server is a Windows Server 2008 R2 SP1 server.

I haven't seen any mention of this issue elsewhere on the forums and a search of the available patches doesn't mention this issue.

Thanks for any help you can provide.
