Error RSPortal: obtaining a connection from the pool
I've worked on this issue with the support. Issue number is 121020321001710.
There is a demo dashboard with Adventure Works Tabular Model and some slicers and filters.
We've fixed the issue by increasing
<MaxCatalogConnectionPoolSizePerProcess> to 500.
This is likely NOT a desktop specific issue. The reason you see the change when saving with a specific version of desktop is likely just the state of the "enhanced model metadata" feature. There is likely an issue with cleaning up unused connections in PBIRS itself. Working with server team to try to reproduce this issue now, but we were running into some trouble getting it to break. Have you seen this issue on a simple report with slicers or has it been on more complicated reports with many visuals + slicers?
For now you can increase the number of connections in the config file as one use suggested, or use reports with enhanced metadata disabled. I will update you when we know more.
Petebro I reproduced the issue as following:
- Create new Power BI report with live connection to tabular model.
- Added 4 visual with existing measures and different dimensions.
- publish it to PBIRS.
- Restart PBIRS to see zero RS Portal connection.
- Start to drilldown/filter visuals and apply filters via filter sections.
- I can see about 2 to 6 new connections for each new combination.
btw: I also tried to switch off the "enhanced meta data" feature but still get the issue.
Petebro I turned off the metadata preview feature, restarted desktop, and created a report with six visuals and one slicer. With each slicer change my connections increased by 6 connections even with the "enhanced meta data" off. So I am seeing the same things as Anonymous.
