[Serusers] Voicemail question

Could someone PLEASE help me with this, it's driving me nuts! Having a strange one since I put voicemail module in. For some unknown reason it fails to connect to the MYSQL database. The original config works fine. Loading ser reports the following: 0(2369) DBT:dbt_cache_get_db:dbtext cache is not initialized! 0(2369) DBT:dbt_init: cannot get the link to database 0(2369) mod_init(): Error while connecting database 0(2369) init_mod(): Error while initializing module usrloc ERROR: error while initializing modules 0(2369) DBT:destroy ... 0(2369) DEBUG: tm_shutdown : start 0(2369) DEBUG: tm_shutdown : empting DELETE list 0(2369) DEBUG: tm_shutdown : empting hash table 0(2369) DEBUG: tm_shutdown: releasing timers 0(2369) DEBUG: tm_shutdown : removing semaphores 0(2369) DEBUG: tm_shutdown : done 0(2369) shm_mem_destroy The mod loads from the ser.cfg are as follows: # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/nathelper.so" # Load accounting loadmodule "/usr/local/lib/ser/modules/acc.so" # load the voicemail module #loadmodule "/usr/local/lib/ser/modules/vm.so" # ----------------- setting module-specific parameters --------------- # -- registrar parameter # special NAT flag indicates that a registered client is behind NAT modparam("registrar", "nat_flag", 6) # -- usrloc params -- #modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 2) Many thanks.
