The SYSV shared memory configuration defaults in the NetBSD kernel
currently have a (too) low value. At least, they do in 1.5.
For -current, I doubled the max. regtion size recently.

You'll have to recompile a kernel, with something like:

	options 	SHMMAXPGS=2048

in the config file, and then this should be ok.
