They cannot assign the memory to oracle after the zfs arc line in /etc/system and there is a lot of free memory during that operation ?
If so, take a look how that user is setuped, especially projects. Solaris uses projects to impose various limits to users projects -l

What is your SGA ?
Are you running your database as a user ? (oracle?)
Are you using zfs filesystems for your database or ASM ?

Zones also have a limit system regarding memory and cpu which is defined in zone configuration file.

This is fairly well documented on oracle site regarding setup of solaris OS for oracle database (global and non-global zones).
Numbers in that documentation are subject to your environment needs.

For instance, in documentation parameter project.max-shm-memory is
4294967295 which is equivalent to 4 GB. This parameter should probably be increased in real life scenario to much higher value (again, depending on your workload, but looks like the errors are coming from there...)

As you might notice, me, as well as others, are guessing
That is not nice from your side, and time consuming from ours.

Hope that clears things out
