[SR-Users] Re: uac_req_send + evroute + crash

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:

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.

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

Does it happen every time or seldom?

Cheers, Daniel
