I found this when doing bulk creating elements and pi tags using AFSDK 184.108.40.20652 (PI AF Services 2017 SP1).
If I create 2000 elements with pi tags, the PIAnalysisProcessor memory usage increases a lot and never get released. If I keep create, at some point, I could not even create one element.(The elements include some attributes, pi tags and calculations)
I'm not sure if this is a PI-AF bug or not. Is there a solution for this?
