Not just you. Specificly, the behavior I see comes about only when Snapshot with a copy of the virtual machine's memory is done. With this box unchecked, there are no problems. I suspect some interaction with the kernel and the openvm-tool set. open-vm-tools-nox11-11.0.1_3,2 I'll upgrade to the latest open-vm-tools-nox11-11.1.0,2 and see if it does it. No change with that version (after a reboot). $ freebsd-version -kru 12.1-RELEASE-p5 12.1-RELEASE-p5 12.1-RELEASE-p5 vCenter server = 6.7U3g I think I'm a little behind on the hypervisor VMware ESXi, 6.7.0, 15160138 So, workaround I guess is to not snapshot the memory, just the disk snap. But still, it shouldn't do that.
