} I have MAXUSER set at 256 and I had OPEN_MAX set at 256. Still I get
} the problem. I notice that setting the OPEN_MAX to 1024 didnt seem to do
} a whole lot.

Hmn, I bet you'll have to recompile apache with the flag
	-DFD_SETSIZE=<something bigger than the default 256>
otherwise select() won't be able to handle and fd's > 255 even though
OPEN_MAX will allow them to be used.

Hmn, you also have to compile a custom version of libresolv.a compiled
with the same flag and statically link it in to your apache executable
because the resolver also uses select().
