WaAppAgent.exe 100% CPU

Question

_{Friday, March 14, 2014 4:10 AM}

Update 04/07/2014 - for VMs that encountered this issue where you have disabled the RdAgent service as a temporary mitigation, you can now download the updated agent as an MSI package from the download site - http://go.microsoft.com/fwlink/?LinkID=394789&clcid=0x409

After installing the MSI package in the VM (same as you would any other MSI package), use the April 2014 v0.8.0 or later Azure PowerShell release to update the VM property to indicate the agent is installed.

$vm = Get-AzureVM –ServiceName <cloud service name> –Name <VM name>
$vm.VM.ProvisionGuestAgent = $true
Update-AzureVM –Name <VM name> –VM $vm.VM –ServiceName <cloud service name>

Now if you run Get-AzureVM again, GuestAgentStatus should be populated instead of blank:

Get-AzureVM –ServiceName <cloud service name> –Name <VM name>

GuestAgentStatus:Microsoft.WindowsAzure.Commands.ServiceManagement.Model.PersistentVMModel.GuestAgentStatus

For a VM to have encountered this issue, among other factors, it would have had to have been created sometime between 2/27 and 3/9. As of 3/10, newly created VMs could've no longer seen this issue since an updated VM agent was being deployed during provisioning after that date.

We are currently investigating an issue where the WaAppAgent.exe process spikes at 100% CPU. WaAppAgent.exe is the process for the RdAgent service, which is part of the VM Agent for Windows Azure Virtual Machines.

If you encounter this issue, you can change the Startup type for the RdAgent service to Disabled, click Apply, then click Stop to stop the service.

If the WaAppAgent.exe process is still running, right-click it in Task Manager and select End Process.

We are continuing to investigate the issue and will provide more information as it becomes available.

Thanks,
Craig
