[Users] Require Core Dump Analysis

[Martin Burns]

Hi,

After many many months of faultless operation, today we experienced a SEG
FAULT on one of our proxies running OpenSER 1.1.0-notls:

Below is a back trace (with some values masked with xxx's), however our
initial analysis can not make any sense of what the problem is. Any ideas
would be greatly appreciated.

res.c:194 is =====>     r = (db_res_t*)pkg_malloc(sizeof(db_res_t));

Here is the back trace:
