Thanks for your workaround solution. It worked and save me some
headache in troubleshooting AG :-).
Yes. Our CPU is a quad core Intel E5420.
We will do more intensive test this week. However, I wonder should I
use your workaround or update to the promised new AG RPM later.
I also thanks Andrew for a troubleshooting of the multicast network
suggestion which we are likely to use if we encounter other problems.
