Hi, we are having performance issues with a Solaris 11.2 server. The memory is reporting as being all in use in vmstat, but prstat does not add up, and zfs arc cache is at a low value. Can you advise what is using the memory?


root@:/opt# prtdiag -v

System Configuration: Oracle Corporation sun4v SPARC T4-1

Memory size: 32256 Megabytes


root@/opt# echo "::memstat" | mdb -k
