Exchange 2010 EdgeTransport.exe process high CPU utilization.

We are running Exchange 2010 in a cluster. One server in a local LAN, second on remote LAN.
Both servers are on SP1, recently we noticed that the CPU usage on the edgetransport.exe service is very high. Whenever we restart the service it goes back to low utilization and then  within few days it goes back to high. Both servers are virtualized and they are assigned 12GB of RAM, 4 vCPUs and IOPs are sufficient.

How to fix it, are the any clues to this, what we should be checking?

Do you have IPv6 disabled on your Exchange server? Also have you disabled it from the registry?

Do the following...
- HKLM\SYSTEM\CurrentControlSet\Services\TCPIP6\Parameters
- Create a new DWORD called DisabledComponents
- Set the value to FFFFFFFF


Also do you have the atleast Rollup 4 for Exchange 2010 SP1 installed?

I would go one step further - install Exchange 2010 SP3 with the latest rollup. Exchange 2010 SP1 is no longer supported and you should upgrade.
