Is there any issues with having multiple ipcs -mb shared segments on a server?

We have upgrade most of our OS to Solaris 10, what I've noticed is that when I do a ipcs -mb I get multiple segments
HOULIVE  > ipcs -mb

Is this normal or is there something I can do to make sure they're all in one segment?

its more of a question, is there any issues with having multiple ipcs -mb shared segments on a server for 1 database, and is there a way to stop it?
