PowerBI Report Server creates minidumps (SQLDmprxxxx.mdmp files)

Dear all,


I have problem with PowerBI Report Server (PBIRS). After updating on version 1.8.7485.35104 (May 2020) PBIRS has started creating mdmp files (see log entry below). At the same time, there is a large increase in reserved memory for reporting and analysis services.

2020-08-31 07:56:40.4291|ERROR|37|PBI.Win.DataExtensionException|ExceptionType:Microsoft.PowerBI.DataExtension.Contracts.DataExtensionException;DataExtensionErrorDetails:Details: Message=Failed to open the MSOLAP connection., HResult=0x80004005, ErrorCode=OpenConnectionError, Language=en-US, ProviderErrorCode=0xC114004C, ProviderErrorMessage=[F80B2ACB1484A8B3FFF8324F72A6CA0F88EDC71C03183680029AFF59B6043AE6], ProviderGenericMessage=[Errors in the metadata manager. Either the database '' does not exist, or you do not have permissions to access it.], ErrorSource=User, ErrorSourceOrigin=MsolapWrapper, OnPremErrorCode=, InnerErrorDetails=[Type=MsolapWrapper.MsolapWrapperException, Message=Could not initialize connection];stackTrace:   at Microsoft.PowerBI.DataExtension.Msolap.Connection.OpenImpl()

 It does not matter the report or the user who accesses the report. The error occurs several times a day. Other times, the reports can be opened without any problems. This error did not occur before the update.


Thank you in advance for your help.
