Thanks for all of the replies. I discovered that ipcs -mo will give me the number of current processes connected to the memory segment. The "dead" segments left by the instance which was giving me problems all had 0 in that column. The segment for the live instance had about 14 processes connected.
I then used ipcrm -m <segment id> to delete the dead segments and restarted the database. Now to figure out why the instance is failing to clean up these memory segments. How did Oracle know that the "shared memory realm already exists"?
