When multiple network interfaces are created in the kernel zone, the ipadm command fails with the following error:
ipadm: cannot create interface net3: Insufficient memory
Workaround: Increase the capped-memory value for the kernel zone. The default value is 2 GB. For example:
# zonecfg -z kzone1
kzone1> select capped-memory
kzone1> set physical=16g
kzone1> end
kzone1> exit
