Yes this is ZFS, I will give your suggestion a try. I do have one UFS system but since I don't have supporting infrastructure for that machine to easily roll back I haven't tested there.The panic you're seeing is caused by 'MPASS(*eofflag != 0);' in vn_dir_next_dirent(). This test is here to check that VOP_READDIR() works properly. In particular, if VOP_READDIR() returned 0 (no error), and the length it filled is 0 (nothing was added), then we must be at EOF, and VOP_READDIR() must have set '*eofflag' to something non-zero. UFS has been verified to abide by this rule (unless the directory being read is malformed). Which filesystem are you using?Shot in the dark & educated guess: You're using ZFS, and you've just stumbled on the following case (lines from 'zfs_vnops_os.c'): /* * Quit if directory has been removed (posix) */ if ((*eofp = zp->z_unlinked) != 0) { zfs_exit(zfsvfs, FTAG); return (0); } which is a corner case that apparently has been missed. Just add some 'if (eofflag != NULL) *eofflag = 1;' inside the "then" block there and retry. It looks like all other cases in this function are handled correctly (but I have not thoroughly verified). I'll be mostly AFK for the next 10 days, so probably won't be able to follow-up, but hope that will help.
