[sr-dev] [kamailio] kamailio 4.3 crash in update_dialog_vars_dbinfo (#301)

[MayamaTakeshi]

Yes. Only one core file. I was running a load test with sipp. When kamailio stopped replying, i found the core file. So I don't think it got overwritten unless it is possible for two processes to segfault at the same time and dump to the same file name.

```
(gdb) p process_no
$1 = 1
(gdb) p pt[process_no]
$2 = {pid = 9251, unix_sock = 12, idx = -1, desc = "udp receiver child=0 sock=192.168.2.185:5060", '\000' <repeats 83 times>}
```

I was testing on a low RAM virtual machine (512MB) with kamailio started with 256 MB of shared mem.
I will start another VM with more RAM and load test kamailio there to try to recreate this: maybe lack of memory caused trouble in the generation of the core file.
