Hello
I am a little busy atm, so before I dig into the code, I have a
question for core devs. Is the LOCK_HASH() call recursive (being
called again from the same process will not block) ? I ask this
because in the 4th blocked INVITE the hash _might_ be blocked by
both t_newtran(#16 0xb7b535fa in t_newtran (p_msg=0x81f18a8) at
t_lookup.c:1064)
No it's not recursive (it will deadlock if called twice for the same
entry in the same process). This is true for all *ser versions
(sip-router, kamailio < 3.0, ser *).
and 6 t_uac (#6 0xb7b6ce01 in t_uac
(method=0xbff60558,
headers=0x81e3108, body=0x81d9afb, dialog=0xa772c6a8, cb=0xb734a622
<publ_cback_func>, cbp=0xa7715158)), thus causing a deadlock.
