Abnormal CPU Usage on Azure VMs with SQL

Hello,

 

For a week, we have noticed abnormal CPU usage on Azure VMs that have SQL Server installed.

 

We observe a link with the Azure SQL backup in the VMs. The CPU load saturates when a backup job is triggered!

 

The backup process iaaSWLPluginSvc consumes a lot of resources, but especially the LSASS process which saturates the CPU.

 

The domain controller is affected by this problem; on it, the LSASS process also saturates the CPU and does not go down! even when the job is finished!

 

Is anyone else experiencing this problem?

 

If so, have you found a solution?

 

We have opened a Microsoft ticket but no response at the moment!
