First off...pick a list, don't send to them all...have narrowed it down to
the only one that was appropriate...

Second of all...Under Solaris 2.6, you have to raise the shared memory
segments available via the /etc/systems file. I don' have the appropriate
document sittin gin front of me, or else I'd try and give you a more
detailed answer, but, for example, one of our Solaris machines at the
office as the following in its /etc/system file:

set shmsys:shminfo_shmmax=16777216
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=51

Each of the values tend to "inter-relate"...so you'll want to read up on
the appropriate docs for this, available through Sun...
