asterisk users - Jul 2008 - 1.4.21.1 SIP failing, requiring reboot

Hi All,

Experiencing frustrating SIP failures on 1.4.21.1.  Everything works fine, and
then randomly after a week or so of use SIP just completely fails to talk to
outside providers and nothing short of a reboot fixes it.

Symptoms:

- both of my SIP providers at the same time become unreachable.  Here is the
most recent time it started from /var/log/asterisk/messages

[Jul 16 05:15:35] NOTICE[27073] chan_sip.c: Peer 'voipplanet' is now
UNREACHABLE!  Last qualify: 15
[Jul 16 05:15:41] NOTICE[27073] chan_sip.c: Peer 'viatalk' is now
UNREACHABLE!  Last qualify: 118
[Jul 16 05:16:59] NOTICE[27073] chan_sip.c:    -- Registration for 'XXXX at
sip3.voipplanet.nl' timed out, trying again (Attempt #1)
[Jul 16 05:17:06] NOTICE[27073] chan_sip.c:    -- Registration for
'XXXXXXXXXX at newyork-1.vtnoc.net' timed out, trying again (Attempt #1)

and it goes on until I catch it... over 12 hours in this case (it's a very
lightly used system)

- sip show peers shows them both as unreachable

- sip show registry shows them both as "request sent"

- internet connection is fine, I can still ping both servers

- reload sip does nothing

- restart asterisk does nothing

- reboot server and it's fine for another week or two

This is 1.4.21.1 on kernel 2.6.25 on a fully updated gentoo system.  The system
is a proof-of-concept system, Asus board, core 2 duo, 2 GB RAM and extremely
lightly loaded.  The two SIP providers are totally unrelated and actually on
different continents.  Any ideas of what I can do to diagnose this problem
further?

Thanks in advance and best regards,

David

Hi David,

It may be IAX2 bug, do you use IAX? In my case downgrading back to 1.4.19
did the job.
