Clarification on UTIL column in "ldm list-domain"

Hi all

Consider the following output on these non-commissioned LDOM hosts on a SPARC T4-2 running Solaris 10 U10 (8/11) Generic_147440-19:

# ldm list-domain
NAME             STATE      FLAGS   CONS    VCPU  MEMORY   UTIL  UPTIME
primary          active     -n-cv-  UART    8     4G       0.2%  2h 18m
uatdoc01         active     -n----  5000    16    16G       88%  3d 6h 19m
uatdoc02         active     -n----  5001    8     4G       0.0%  1d 8h 9m

What exactly is the UTIL column and why would host uatdoc01 be a constant 88% ?  It doesnt seem to be CPU, as when I log into the host itself or use "ldm list-domain -e uatdoc01" it is practically idle at 0.2%.  I was thinking maybe a bug?

# ldm -V
