[Steps]
1. one MCU call multi-endpoints
2. MCU hangup all endpoints
repeatedly. And all through Kamailio proxy.
[Results]
For a while, Kamailio crashed.
Followings are related logs:
==========================================
Sep 2 19:08:34 ./kamailio[3712]: : tm [t_fwd.c:1632]:
t_send_branch(): BUG: t_send_branch: retr. already started
for 0x41848fa0
Sep 2 19:08:34 ./kamailio[3712]: ERROR: sl
[sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error
used: Unfortunately error on sending to next hop occurred
(477/SL)
At this point the related behavior is that Kamailio
received two INFO requests simultaneously. I wonder whether
this is the cause.
And maybe it's related to the later crash?

Any suggestions?
Thanks.
