There is a section in the memory usage guide mentioning such an effect, but that's for "a long time", whereas I already notice the memory usage at 3.5 GB after less than 6 hours of use. Therefore there must be something that exacerbates the problem, which I haven't been able to figure out. For more information I've uploaded two anonymized memory reports: https://www.dropbox.com/s/ot1an2hdjqptqrt/memory-report.anonymized.after_startup.json.gz?dl=0 https://www.dropbox.com/s/oajyd6od2d4k46b/memory-report.anonymized.6h.json.gz?dl=0 If someone has an idea how this could happen, I would be very glad to hear it! And of course please don't hestitate to ask for more information.
