Hello,

do you also get error log messages that include "failed to send request with authentication"?

Which CRITICAL log appears when you call uac_req_send()? You pasted a couple of them in the initial email?

Cheers,
Daniel

Hello,

 

I used kamailio version 5.6.2. I refreshed to 5.7.2 today.

As I remember it was in kamailio long time ago therefore I could skip evroute route.

But this CRITICAL log appears always when I call uac_req_send().

I call it with settings:

$uac_req(auser) = $var(username);

$uac_req(apasswd) = $var(password);

 

Where username and password are retrived from web service before call.

In event_route I got first 401 after 200.

 

Peter

Hi All,

 

I use kamailio In front of Asterisk and kamailio needs to refresh registrations periodically towards Asterisk to ensure the availability of users from Asterisk side.

I use uac module and call uac_req_send() for sending REGISTER requests.

I set $uac_req(evroute)=1

 

The event_route[uac:reply] is called fine, but in kamailio logs I see the next lines:

 

CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) - ignoring

 

After some time, kamailio has crashed.

CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 34

ALERT: <core> [main.c:774]: handle_sigs(): child process 1407950 exited by a signal 6

what version of Kamailio are you using? Is Asterisk challenging for authentication?

Does it happen every time or seldom?

Cheers,
Daniel
