[Freeswitch-dev] coredump (dingaling)

Thu Dec 17 14:41:37 PST 2009

Hi all,

Bug-rapport is submitted:
http://jira.freeswitch.org/browse/LBDING-18

This is a traceback I got when the problem accured when freeswitch
crashed when the gtalk-session was TERMINATED.

One of the things I did notice was this:
2009-12-17 11:42:45.461750 [ERR] switch_rtp.c:370 Invalid STUN/ICE
packet received
During some other voip-sessions, I got loads of these messages; however
I do not have this problem always.

One of the strange things I did notice is that in the packet captures I
took (on the server) I see UDP-packets for 69.0.208.27 udp/3478 (that's
stun) with incorrect CRC-checksum; or at least, that's what fireshark
tells me. The strange this is that I do get a UDP STUN-packets back
(which is strange as normally a server on the other side should ignore
UDP-packets with errors in it).

BTW.
Another elements this is strange:
Audio-traffic from the sip ATA to the mac flash/webinterface is almost
immediatly. Audio-traffic in the other side has about a 1 second delay
But this could be a problem on the webinterface flash-application, not
network related; so I do not know if this is related to this problem.

Cheerio! Kr. Bonne.
