It means that somehow the UFS code got a request to rename a file to itself, and the kernel code didn't think it was possible for such a request to get into the kernel. [e.g., the mv(1) command checks for that before issuing the system call, so it can't happen that way] The error *is* handled cleanly, so it isn't necessarily a problem, but if you figure out what's causing it, preferably in a way that someone else can reproduce, please report it. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
