Hello Daniel,
I do not see any “failed to send request with authentication”.
The next CRITICAL log appears after calling uac_req_send():
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
Now we use kamailio 5.7.2 and no crash has come, but the critical logs above exist.
I saw a ticket in github: https://github.com/kamailio/kamailio/issues/3522, may the crash
be similar or the same to that?
I will make a try next week with downgrading to 5.6.2 and try to reproduce the crash.
Peter

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.

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

After some time, kamailio has crashed.

what version of Kamailio are you using? Is Asterisk challenging for authentication?
Does it happen every time or seldom?
Cheers,
Daniel
