Thank you Andrew. Are there any special instructions for using valgrind
with S4? Or can I just do like I would with any other program and just
put valgrind before with --memcheck=full (I probably have that a bit off)?

The use-after-free() is still happening it seems under load even with
the off-line-files gone, so I think I should be able to duplicate it.
(In fact it seems to be more related to the "destination unreachable" I
mentioned an hour or so ago.)
