[Serusers] Voicemail config producing errors and zombies

All, I've been working on voicemail for a while, and haven't made much progress. In looking through the archives I've come up with a few example configs. My latest attempt gives me a number of errors. I was hoping some of the experts could help out with where I'm going wrong. I'm still in a test mode, so there are only 2 people registering. When I try to start ser, I get the below errors, and a large number of Zombie processes: Sep 10 15:46:52 enforcer ser[30812]: connect_db(): Too many connections Sep 10 15:46:52 enforcer ser[30812]: db_init(): Error while trying to connect da tabase Sep 10 15:46:52 enforcer ser[30812]: ERROR; vm_init_child: could not init db mys ql://ser:heslo@localhost/ser Sep 10 15:46:52 enforcer ser[30812]: init_mod_child(): Error while initializing module voicemail Sep 10 15:46:52 enforcer ser[30812]: init_children failed My config looks like this: # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode debug=7 fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #port=5060 #children=4 fifo="/tmp/ser_fifo" fifo_mode=0666 alias="nysernet.org" alias="enforcer.nysernet.org" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/vm.so" loadmodule "/usr/lib/ser/modules/group.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # -- 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) # -- auth params -- # Uncomment if you are using auth module # modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # -- tm - fail on invite -- modparam ("tm", "fr_inv_timer", 30) # -- voicemail params modparam ("voicemail","db_url","mysql://ser:heslo@localhost/ser") # ------------------------- request routing logic ------------------- # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("enforcer.nysernet.org", "subscriber")) { www_challenge("enforcer.nysernet.org", "0"); break; }; save("location"); break; }; }; # Is the user in the voicemail group?
