Re: [SR-Users] crash after using async_route()

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. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
