FreeBSD has historically had issues with the default clock timer. A clock that's not running right can screw with the machine's perception of time intervals, and thusly with CPU usage calculations. on the CLI run:
sysctl kern.timecounter.hardware if the result is: kern.timecounter.hardware: HPET then this is likely your issue. to see your clock choices, run this command, and you should get the resulting output as below: sysctl kern.timecounter.choice kern.timecounter.choice: TSC(-100) i8254(0) ACPI-fast(900) HPET(950) dummy(-1000000) The numbers are how preferred the given timer is. ACPI-fast will usually show up on a VM running on top of ESXi. When I switched my problematic FreeBSD VMs to ACPI-fast, all my weird phantom issues went away... no more phantop pegged CPUs or hung machines. -Ian On Tue, Aug 21, 2012 at 11:06 AM, Marc R.
