wdoekes, in your case at least (and probably beres'), it looks like the
leak happens only on T.38 sessions, as ports leaked seem to always be by 3
looking at the information you provided (I can't believe i missed that
before!):

- an RTP port (10000-20000)
- an RTCP port (RTP+1)
- a UDPTL port (4500-4999)

Ex. from about everything you pasted, you can see it clearly things like:
asterisk 13620 asterisk 30u IPv4 66394165 0t0 UDP *:14418
asterisk 13620 asterisk 31u IPv4 66394166 0t0 UDP *:14419
asterisk 13620 asterisk 32u IPv4 66394167 0t0 UDP *:4552 

You can try to confirm by disabling T.38 if you can. In that case the good
news is it would narrow the problem down quite a bit.

The bad news is I'm no expert at all in all the REF/UNREF things in
Asterisk, I will try to get a look and help, but probably a real Asterisk
dev will have to correct the issue, and believe me this could take time
(start learning C, that's what I did while waiting for answers on this bug
tracker). :-)
