    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

Hi S-Driancourt,

 

Based on my test with the http://<IP address>/OLAP/msmdpump.dll in latest desktop version 2.44.4675.521 and service, all visuals can display fine in the report. Please try to use the same desktop version as ours.

 

From the error message, the issue should be related to the SSAS server or IIS server. Please check logs generated on that two servers side to see if any issue occurs at the tome that error throws out. Verify both SSAS and IIS service are running. 

 

Best Regards,
Qiuyun Yu
