Power BI Premium Capacity occasional extremly long refresh

We have been experencing occasional long refreshes on our preimum capacity.  Our data set refreshes 80 times a day and ususally takes 2-3 mintues.  Every once in a while we have gotten extremely long refreshes.  30 minutes to 1.5 hours.  The long refrehes can causes critical business delays

  • Logs
    • The logs for these long refreshes dont seem to explain much as there are no errors.  
    • The longer 1 - 1.5 hour versions stop logging entirely for the middle of the refresh and pick back up again right at the end.
    • The count of log enteries is not signifganly different than a normal refresh. 
  • Capacity
    • The Preimum capacity is in a normal state and not near its maximums.  
  • Support
    • Power BI service has not been able to provide us with any explination of why it has happned.

Current soloutions

The only solution we have found to this issue is to take the workspace out of the preimum capacity wait five minutes and put it back in.  


if anyone has any thoughts on this behavior it woudl be helpfull.

If you have a Premium capacity, I would create a support ticket with Microsoft and get them to help with analysis.

Hi @3CloudThomas great point!!! We have created several support tickets as we have encountered this issue.  Microsoft has not been able to provide a satisfactory solution.
