After upgrading to ESXi 6.5 many of our guests (Windows and Linux) are showing an increase in Host consumed (Active) memory. A couple routinely reach alarm status which they never would have come close prior to the upgrade. Support has been investigating for a couple of weeks but has not come to any conclusions. I'm wondering if anybody else is experiencing the same. From the image attached - we upgraded on 2/9/17. The dips back down occur upon rebooting the guest or vMotioning to another host (which is how I'm currently clearing the alarms). This is one of the drastic ones. Most others are ~50%-100% increase.
Thanks,
Brett
