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.

Any idea that is it a bug or I use something wrong in config?
Thanks in advance!

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

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.

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 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
