One of our customers, who is using the Windows GUI (2019.2.17), is using up to 9 GB (!) of internal memory on the RDS with TSF_dotNET.exe. Most of the time TSF_dotNET.exe is using around 2 GB, but that is also too much.
How is this possible and how can we limit this?

Johan and I analyzed this issue together. For future reference; huge memory increase is to be explained by opening the E-mail subject, (in excess of 10000 rows) containing HTML data. A new E-mail subject was opened every time a ‘Werkbon’ was processed (Process flow). Therefore the memory usage keeps increasing.
Only a few E-mail rows are actually needed during execution of the process flow so a workaround for the problem at hand is implementing (better) prefilters or setting a max no of records for the E-mail subject (platform > 2019.1).
Why memory is not released when closing a subject will be investigated by us.
