Summary: Asterisk segfaults when using SIP session timers
Description:
My Asterisk 1.6.0-rc6 shows the same symptoms as in issue 0012919: under
moderate or heavy traffic it keeps crashing randomly about every half an
hour.
Inbound traffic is coming from a single equipment (not under my control)
that always sends "Session-Expires" in the SIP packet. In the additional
information I enclosed a typical incoming packet.
I set "session-timers = refuse" in sip.conf [general] last friday and it
didn't crash anymore in about three days. after a so long time without a
single crash I think that we can say that it fixed the problem.
I collected 23 core dumps in about 10 hours, it is a production machine
that suddendly started crashing and I had no time to recompile and enable
thread debugging as recommended. In the additional information I enclosed
all the backtraces.
The backtraces show that the crash is mostly inside proc_session_timer(),
but in different lines, as if p->stimer disappears just after the initial
consistency check (maybe the channel is closing exactly when the timer
expires?).
Should you need the core dumps (about 130 Mb), I can send them to you
privately, they contain lots of confidential data and I can't make them
public.
