crash after using async_route()

by Vitaliy Aleksandrov

Hello kamailio list, Recently found a problem in my configuration that uses async_route() functionality. It crashes after several calls when wait_timer fires. #0 0xb74a8556 in raise () from /lib/libc.so.6 #1 0xb74a9d78 in abort () from /lib/libc.so.6 #2 0x08293ae2 in qm_free (qmp=0xad65d000, p=0x3d64692d, file=0xb6216a16 "tm: h_table.c", func=0xb621663c <__FUNCTION__.18751> "free_cell_helper", line=187, mname=0xb621664d "tm") at core/mem/q_malloc.c:471 #3 0xb613f103 in free_cell_helper (dead_cell=0xae2cd210, silent=0, fname=0xb6239ea5 "timer.c", fline=655) at h_table.c:187 #4 0xb61e7758 in wait_handler (ti=557858937, wait_tl=0xae2cd258, data=0xae2cd210) at timer.c:655 #5 0x0826a2cc in timer_list_expire (t=557858937, h=0xad6b9668, slow_l=0xad6ba144, slow_mark=312) at core/timer.c:874 #6 0x08267cb1 in timer_handler () at core/timer.c:939 #7 0x0826a4d3 in timer_main () at core/timer.c:978 #8 0x08069575 in main_loop () at main.c:1721 #9 0x080707ca in main (argc=11, argv=0xbf85f044) at main.c:2723 When crash happens, kamailio prints the following message: Sep 4 16:15:38 [18938]: : <core> [core/mem/q_malloc.c:469]: qm_free(): BUG: qm_free: bad pointer 0x70707553 (out of memory block!) called from tm: h_table.c: free_cell_helper(187) - aborting Also had a few crashes in retransmission_handler(): #0 0xb750b556 in raise () from /lib/libc.so.6 #1 0xb750cd78 in abort () from /lib/libc.so.6 #2 0xb6249b5a in retransmission_handler (r_buf=0xae036674) at timer.c:367 #3 0xb6247558 in retr_buf_handler (ticks=1234464444, tl=0xae036688, p=0x1f40) at timer.c:594 #4 0x0826a2cc in timer_list_expire (t=1234464444, h=0xad71c668, slow_l=0xad71cd44, slow_mark=2232) at core/timer.c:874 #5 0x08267cb1 in timer_handler () at core/timer.c:939 #6 0x0826a4d3 in timer_main () at core/timer.c:978 #7 0x08069575 in main_loop () at main.c:1721 #8 0x080707ca in main (argc=11, argv=0xbff64134) at main.c:2723 ERROR: tm [timer.c:366]: retransmission_handler(): transaction 0xae0365e0 scheduled for deletion and called from RETR timer (flags 6d) Both timers fired for an INVITE transaction that was previously suspended by async_route(), then resumed, sent out and received a 4xx reply (407). This configuration worked fine with kamailio 4.2.x and problem appeared after upgrading to 5.0.2. Trying to figure out how to narrow down the problem. Any input is appreciated.

handle_tcpconn_ev(): connect failed

by Donat Zenichev

Hi. Recently I've come across with TCP connection problem. The topology is as following: DNS srv load balancer - two kamailio proxy servers - one routing server. Client appeals to NAPTR record like: sip.domain.com So dns returns one of the proxy servers to client (depending on weight/priority). Now both kamailio have the same priority and weight (the goal is load balancing). Routing server (now it is asterisk) working with chan_pjsip.so, that supports NAPTR/SRV records. He is able to resolve Record-Route / Route headers with value - sip.domain.com (that proxy servers add to record-route headers while relaying requests to him). This topology is done to support present dialogs, even if proxy that recently processed it, is dead. But the problem comes, when routing server (asterisk) sends in-dialog requests to the proxy, that wasn't used to establish the dialog. Example, routing server obtains 200 OK from endpoint (relayed by kamailio1 to him) and he sends back ACK, but not to the kamailio1, he sends it to kamailio2 (because he resolves NAPTR sip.domain.com and gets ip of second kamailio). Kamailio2 processes the request as usual, because both kamailio have the same db for dialog module, but when he tries to relay the request to endpoint, he gots the error: ERROR: <core> [tcp_main.c:4070]: handle_tcpconn_ev(): connect XXX.XXX.XXX.XXX:52185 failed The port that kamailio2 tries to use to relay the ACK, is port that endpoint used to establish the dialog with kamailio1 and actually his TCP connection is now established with kamailio1. So kamailio2 tries to use the same port and gets the error. And this is proper behavior I think. There is no problem with UDP transport. Has anyone seen the similar problem? That indeed is not a problem, but proper behavior. -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

cr failure routes

by Nelson Migliaro

Hello, I am using carrierroute in Kamailio (great module btw). All calls go the same gateway (rewrite_host). I am routing over differents vendor using a prefix. Prefix: 21 dnis: 999999999 $rU after rewrite_host is 21999999999 My problem is when trying to use a failure route, next domain use a different prefix but the host. So I get the: Candidate destination <gateway> was previously used Is there a flag or something to prevent this verification ? Thank you Nelson.-
