Random fail acces to report

Hello,

It happens that for some of our reports their access fails. After a few seconds of waiting, the access was successful. How to find the cause? 

I check all logs files (RSHostinService, RSmanagement, RSPowerBI, ASManagedRoot, ReportingServicesService, msmdsrv)

Someting, cpu went to 100% and msmdsrv.exe and some Microsoft.Mashup.Container.NetFX45 principals consumer.
