SQL Server 2008 R2 hangs when adding perfmon counters

System is Windows Server 2008 R2 Enterprise 64 bit Running Microsoft SQL Server 2008 R2 (SP1) - 10.50.2425.0 (X64)

This is a newly built and deployed server, operating in an active/passive cluster. Dual Xeon procs, 64gb RAM, C drive is local Ra开发者_Go百科id 1, all other volumes are DAS.

Often when I run perfmon, and click on the green plus icon to add counters, perfmon hangs for 3-4 seconds, and SQL Server hangs completely for about 60 seconds.

This is somewhat intermittent, but has happened 5 times in 2 days. perhaps half of the times I've run perfmon. I'm naturally hesitant to cause this issue purposefully as this is our production system.

Any thoughts?

This issue was caused by running the Community Technology Preview version of SQL Server 2008 R2 SP1.
