No Free Addresses?

No.  But that would not have addressed the primary problem of not
having enough IP addresses available.  Each machine in the failover
pair needs to be able to independently support the entire network.  If
that only happens by manually putting one machine into partner-down
then that isn't a truly redundant system.

Putting the single server into partner-down would have increased the
pool size the same as I did manually.  But then I am still left with
the same questions about how big of a pool do I need and how can I
tell?

But that also opens a second less important issue that I hadn't
debugged yet.  When I tried to use omshell to do that it failed to
connect.

  # omshell

I wasn't able to talk to the running daemon to actually switch it to
partner-down.

When I strace'd the operation I get the following result.

  connect(4, {sa_family=AF_INET, sin_port=htons(647), sin_addr=inet_addr("172.17.17.210")}, 16) = -1 EINPROGRESS (Operation now in progress)

I consider this a separate issue but since you asked any hints there?
