> Server has been up for 50 days and regularly handles 60 concurrent calls (we have other busier servers). Today we had a core dump. 
> In the asterisk logs :-
> [Oct 14 15:55:53] ERROR[1650] astobj2.c: bad magic number for 0x7fb67452dad8. Object is likely destroyed.
> Kernel messages :-
> Oct 14 15:55:53 gw3 kernel: asterisk[1650]: segfault at 18 ip 00000034f1f3b8ff sp 00007fb679908088 error 4 in libc-2.12.so[34f1e00000+18a000]
> Oct 14 15:56:00 gw3 abrt[7599]: Saved core dump of pid 1630 (/usr/sbin/asterisk) to /var/spool/abrt/ccpp-2013-10-14-15:55:53-1630 (171835392 bytes)
> I see that there is a newer glibc 2.12-1.107.el6_4.4 available.
> Please could you advise if its an asterisk issue or definitely a fault with glibc. I will upload the core dump shortly.
