I couldn't post the snippet as it fails the sensitive language check... So I try to add it as text file [here] leaks.snippet.txt

Short update, Beta 3 did not fix the issue unfortunately, we updated the linked Feedback accordingly.

Hi, It looks like the issue is fixed, or at least its impact is reduced. After leaving my MacBook running tonight it accumulated no significant amount of Memory. Still leaks is reporting some leaks. We will provide a leaks report from a device with Sequoia and obviously from the 26.4 device in the Feedback. Best regards, Timo

Ok I have to correct myself, after a few more hours using the MacBook and switching networks the Memory utilization increased again. Our NEXT is now at 1.8GB and socketfilterfw is at 1.2GB. It seems to be slower but there is still a leak.

Hi, I held off creating the new feedback until I was able to reproduce the issue again so the sysdiagnose is actually from when the system is in the state where it is leaking memory. Today I managed to reproduce the issue again. I did open a new feedback FB22050795 with a fresh set of leak reports, samples and some lsof's attached. Best regards, Timo
