You can either fix them or shut them up. Fixing them is greatly preferreable because fixing them is rather expensive (the app traps into the kernel, which fixes up the access). See the uac(1) man page. If you want to fix them, use uac -s & run gdb on the app. If you just want to shut up the warning, use uac -p. As to why you see them on FreeBSD & not linux; I think some linux distros may come with uac printing turned off...
