Revit 2023.1 memory leak at PDF export?

[adamCYHL9]

Hi,

Mostly curious if anyone else has the same or similar experience.

We've got a fairly simple building with around 80 flats. Filesize is around 90MB at the moment. After publishing (Export to PDF using Revit's built-in tool) a set of plans - vector floor plans/sections and rasterised perspective views - the memory usage of Revit jumps from around 2GB to 20GB and more. The worst thing is, even after the export is done, it stays that way. If after making design changes to the project I want to reexport the plans (even if just a selection) I run out of memory, the graphic driver crashes/restarts, resulting in wrong colors on the rasterised plans.

color difference - driver crashed mid export. Left is the correct look, right is after graphic driver restartedAftr opening Revit file, fairly normal RAM usageAfter export. Bottom left are visible the PDFs after crashed graphics driver. RAM and Pagefile are full to the brim, never emptying.

Looking forward to any tips. Right now I can close and reopen Revit after every export, but it's tedious and not sustainable.

Nvidia Driver Version is the latest, ie. 528.89 for Quadros.
