any shared memory problems known with amd64 port? having problems with pgcluster 1.07

[Tomaz Borstnar]

Hello!

	I am having problems starting up pgcluster (multi-master replication 
version of postgresql 7.3.x) on FreeBSD 5.2.1-p9/amd64. It complains like 
it does not have enough semaphores. Current settings are:

kern.ipc.semmni=80
kern.ipc.semmns=480
kern.ipc.semmnu=240


but I started with half of that (as per suggestion of one of postgresql 
ports). shm is set:
kern.ipc.shmmax=100663296
kern.ipc.shmall=24576


initdb is done succesfuly but start fails. postgresql-devel port seems to 
work fine, but this is based on would-be postgresql 7.5.

So am I wondering whether i can expect shared memory problems  in amd64 mode?

Thanks in advance.
