I was afraid something like that might happen - the latest snapshots
increase the max. size of messages that Hobbit can handle to acommodate
some of the larger messages that clients may send.

You need to tweak a kernel tuning parameter for your Mac OS X / Darwin
kernel. From a bit of googling it seems this is done very much like the
way you'd do it on FreeBSD - i.e. using the "sysctl" tool.

Could you try running (as "root" or whatever that's called on Darwin):

   for P in shmall shmmni shmmax; do sysctl kern.ipc.$P; done

and also the "ipcs -m" command to list the current shared memory 
segments.
