Yes.

But then again, for such a simple call (a single INSERT) you can use a
MySQL() from the dialplan.

And this is also basically the same as adding a CDR record. Which is why
I guess you can probably use the existing CDR code.

So no processes are currently in state 'D' (the two processes here are
grep itself, and an unrelated daemon, both in state 'S', which is the
normal 'Sleeping').

(So your issue was merely the fact the the CPU was flooded with work,
and not some processes hung in uninterruptable sleep).

* Killing a process in state D is generally pointless (it is in an
  uniteruuptable system call: not even kill -9 would get it).
* That process was not in state D anyway :-)
