    Thank you very much Qiuyun Yu for your feedback.

    We just found the solution to our issue and you were right, the issue was coming  from the IIS Server, or mor precisely from the configuration of the msmdpump.

    We read the following article:

    http://amolpandey.com/2016/08/26/ssas-msmdpump-dll-failing-occasionally-under-high-user-loads/

     

    And we added the following 3 lines in the msmdpump.ini file

    <MinThreadPoolSize>0</MinThreadPoolSize>
    <MaxThreadPoolSize>0</MaxThreadPoolSize>
    <MaxThreadsPerClient>20</MaxThreadsPerClient>
     
    Now we do not have the issue anymore, in Power BI Desktop or in Power BI Services
    Best regards,
    Sylvain

Thanks Sylvain for your answer. 

 

Did you ever encounter the impossibility to live connect to the pump using that method? From day one, we're not able to connect this way. In Excel or Tableau we have no problems. 

 

 

Microsoft even say the live connection is not supported in this recent thread I made: https://community.powerbi.com/t5/Desktop/Any-timeline-on-when-a-live-connection-to-a-msmdpump-dll-SSAS/m-p/231183

 

So I'm actually surprised you managed to live connect to your msmdpump.dll 

 

What steps did you take for it to authentify you correctly? 

 

Thanks

Dear Tannera,

I had this kind of message in the past when I first tried to get live query with msmdump.dll.

One day, just to show the error message I had I tried again and it worked.
What I had changed in the meantime was:

- the version of PowerBI desktop

- the version of SQL Server (2008R2 -> 2016 SP1)
