mfs has to allocate a chunk of RAM for the filesystem, and if it can't
allocate one big chunk of N megabytes of RAM, it can't run an MFS
filesystem of N megabytes in it - even if the reason for that
allocation failure is something other than lack of VM or RAM.

Is 247M anywhere near any of your per-process resource limits, by any
chance?
