oracle handing memory allocation different between 11g and 12c?

OS: Solaris 10 running on a zone of a T-4

I'm attempting to upgrade a database from 11.2.0.4 to 12.1.0.4

After running all prerequisite checks and resolving issues, I'm ready to run the upgrade

Starting the database using the 12c software, I'm getting the following

SQL> startup upgrade
ORA-27125: unable to create shared memory segment SVR4 Error: 22: Invalid argument

Additional information: 2634
Additional information: 4194304
Additional information: 4194304

Sga_max_size is 1 G (same size used when database was 11g) Sga_targeet is 1 G

(lowering both of these to 500 Meg makes no difference)

Ipcs -a shows roughly 2.5 gig being used by other 11 g datbases on this server.

/etc/project has
user.oracle:100::oracle::project.max-sem-ids=(priv,100,deny);project.max-shm-memory=(priv,5368709120,deny);rcap.max-rss=19327352832

(which I understand to mean that the total of all shared memory segments is limited to 5 Gig.)

Is there something different between the 11g and 12c versions that might explain this?

The alert log is showing:
