[OpenSER-Users] Usrloc db_mode = 3 (DB_ONLY)

Hi, I am just getting started with openser (using openser-1.2.1) and have run across a problem I cannot seem to solve. When using db_mode=2 for the usrloc module, everything works fine. However, when db_mode is set to 3, calls are not able to be made - it seems that lookup("location") always fails. I see this in the log: Jun 25 16:35:17 cobalt1 /usr/local/sbin/openser[10084]: check_response(): Authorization is OK Jun 25 16:35:17 cobalt1 /usr/local/sbin/openser[10084]: check_username(): Digest username and URI username match Jun 25 16:35:17 cobalt1 /usr/local/sbin/openser[10084]: DEBUG:usrloc:db_load_urecord: aor not found in DB Jun 25 16:35:17 cobalt1 /usr/local/sbin/openser[10084]: lookup(): '1002' Not found in usrloc Having checked the mysql query log, the query that was run is: 130 Query select contact,expires,q,callid,cseq,flags,cflags,user_agent,received,path,sock et,methods, last_modified from location where username='1001'order by q If I run this query myself at the mysql command prompt, I get exactly one row returned: +-----------------------------------------------------+----------------- ----+-------+-------------------------------+-------+-------+--------+-- ----------------------------+----------+------+---------------------+--- ------+---------------------+ | contact | expires | q | callid | cseq | flags | cflags | user_agent | received | path | socket | methods | last_modified | +-----------------------------------------------------+----------------- ----+-------+-------------------------------+-------+-------+--------+-- ----------------------------+----------+------+---------------------+--- ------+---------------------+ | sip:1001@192.168.0.25:5062;transport=udp;user=phone | 2007-06-25 17:34:59 | -1.00 | bd348eeee82e4349(a)192.168.0.25 | 20092 | 0 | 0 | Grandstream GXP2000 1.1.2.27 | NULL | NULL | udp:172.16.1.1:5060 | 8063 | 2007-06-25 16:34:59 | +-----------------------------------------------------+----------------- ----+-------+-------------------------------+-------+-------+--------+-- ----------------------------+----------+------+---------------------+--- ------+---------------------+ 1 row in set (0.00 sec) Having followed through the code, in modules/usrloc/udomain.c (about line 550), things seem to be going wrong for me in this bit of code: if (ul_dbf.query(_c, keys, 0, vals, columns, (use_domain)?2:1, 13, order, &res) < 0) { LOG(L_ERR, "ERROR:usrloc:db_load_urecord: db_query failed\n"); return 0; } if (RES_ROW_N(res) == 0) { DBG("DEBUG:usrloc:db_load_urecord: aor not found in DB\n"); ul_dbf.free_result(_c, res); return 0; } I tried to find out why this is happening by attaching with gdb, but when I try to view res or res->n, I get a message that variable res is currently unavailable - I'm not sure if this is something to do with the way I'm using gdb though. When I step through, RES_ROW_N(res) == 0 must be true as it enters the code within the {} instead of skipping over it. Could anyone point me in the right direction as to why this doesn't work please?
