[Asterisk-Users] Asterisk freezing HELP

[mattf]

Hello,

I've continued to have lockups since last week and this is really beginning
to drive me crazy. Could this be a problem with specific hardware or a
specific setting in the configuration files that causes these lockups for
some and not others? If everyone that is experiencing Asterisk lockups would
email me their setup:

- system hardware/software i.e.(ASUS w/P4 2.6 GHz 2GB DDR RAM - Redhat 9.0
SMP)
- hardphones/softphones they are using and how many
- Zap hardware they are using and what is hooked up to them
- send me extensions.conf and sip.conf files

I will attempt to figure out what is common amongst the unlucky and submit
my findings to the list

If anyone that has had no lockups for at least a month would like to send me
the above information that also may help me as well.

Thanks for your help,

MATT---

Hi TC,

I followed your instructions.  Today I managed to lock up one of our
Asterisk boxes with an incoming SIP call.

It locks up right after seeing I this line:
Dec  8 13:48:34 WARNING[4101]: File chan_sip.c, Line 456 (retrans_pkt):
Maximum retries exceeded on call fc19b3c44627f4d6 at 192.168.0.160 for seqno
1058 (Response)

I was able to follow down to STEP #7 of your Deadlock debug Instructions,
but the file in step #8 is not present.

In any case here is the relevant thread that is locked:
Thread 6 (Thread 4101 (LWP 8372)):

#2  0x4003b4b9 in __pthread_alt_lock () from /lib/i686/libpthread.so.0
(gdb)

Is this enough to open a ticket in the BUG tracker?

Is there anything else I should look for?  I have not restared Asterisk yet.

Thanks,
Andres.
