[Users] Require Core Dump Analysis

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: (gdb) bt #0 0x00000000 in ??
