Lowering the Cap of an Lnode
The limadm(1MSRM) command can be used to lower the memory cap of an lnode, which makes the cap more restrictive. rcapd will enforce the new cap after the next configuration interval (see rcapadm(1MSRM)). A signal can also be sent, which causes rcapd to enforce the new cap immediately.
admin# limadm set rss.limit=30M user1 admin# pkill -HUP rcapd |
The following command produces reports at 5-second sampling intervals. A report will be issued five times, once after each sample.
admin# rcapstat 5 5

When the cap was lowered to 30 megabytes from 50 megabytes, rcapd responded by attempting to page out the 6-megabyte amount of resident memory above the cap value. The goal was reached; it was exceeded by a small amount.
