If these messages are describing about your /rw tmpfs, then it means the
spaces for the file you removed before remounting are not freed
yet. Right? One or more processes still are still holding a file
descriptor corresponding to that file, I am afraid.
Can you confirm it by "df /rw" between rm and remount?

If the cause of those messages is related to aufs XINO files (which are
not so large), then putting the XINO files in another tmpfs will be
effective.
Altenatively, a simple remount before your /rw gets full may be
effective too. It will prevent aufs to write XINO files at remount-time
after /rw got full.
