Could you please provide straces of the ifdown -a call using '-p' to trace
the children? Because the error strace ends with:

clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x401632e8) = 20028
waitpid(20028, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0) = 20028
--- SIGCHLD (Child exited) @ 0 (0) ---
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x401632e8) = 20033 waitpid(20033, <unfinished ...>

Which prevents us from reviewing what exactly happened to the chile and why
does it stall.... I know this is a major issue (you will need to reboot the
system) but it probably could help debug the issue better.
