Microsoft Mashup Evaluation Container - over 100 instances running on my virtual machine

Hello all,

     I have an instance of SQL Server on a virtual machine that is used as a source of data for our organization's PowerBI online service (pro license).

We use the PowerBI enterprise gateway hosted on the virtual machine to automatically refresh our PowerBI dataset.

After some time, maybe a month or so, I will have terrible issues running SQL Queries. When I log into the virtual machine where SQL Server is hosted, I see that all of it's memory is being taken up by several dozen 'Microsoft Mashup Evaluation Container' processes.
I am not sure what these are about, but I have to restart the server to end these processes and move on.

Can someone explain to me what these processes do and why they are multiplying on the virtual machine? I suspect it has something to do with the Enterprise Gateway and the automatic refresh?



Thank you

I am the PowerBI developer. We are refreshing 2 datasets everyday, one is on an enterprise GW and the other is on a personal gateway. The refreshes usually always happen successfully, so I am not sure why these processes linger after the refresh.
I have resorted to running a Powershell script to terminate these processes as they accumulate;
stop-process -Name "Microsoft.Mashup.Container.NetFX45".
I would prefer to understand how to stop these containers from lingering on the server after the refreshes are successful. Any advice would be appreciated!
Thank you

If you have a Pro license then I would suggest you raise a Pro ticket at so that Microsoft can have a look.  


This is actually one of the reasons why it is not recommended to run the gateway on a shared resource. Gateways don't like to share.

These can either be import queries or Direct Query queries.  Ask the Power BI developers about their dataset refresh experience (long refresh durations, refresh failing with timeout etc).  Most likely these are abandoned refresh sessions that SQL Server is too afraid to kill.  Work with the developers to improve their refresh performance.
