    Running Mac OS 26.4, Parallels 26.3 with Win 11 VM. Throughout the day the memory on Mac OS keeps increasing. VM is set to (6) vCPU and 16GB memory. Last couple days VM was well over 100GB memory. Eventually VM becomes unusable. I see some old posts around, no solutions. Thoughts?

    Shut down VM and MBP last night. Started up at 09:00 today. Not a have workload. And it's been creeping up all day.

    Wanted to let community know, I tested between two different MBP M5 Max machines and problem persisted. Parallels Team had me build a new VM and the problem persisted. Was able to share some screenshots and diagnostics with them. They advised me to install ParallelsDesktop-26.2.2-57373.dmg. Ran all day today and zero issues with memory.
