[Serusers] receive_msg: no mem for sip_msg

Hi, When I put these lines in ser.cfg : modparam("usrloc", "db_mode", 1) modparam("usrloc", "db_url", "mysql://ser:heslo@localhost/ser") Then I get this error each time my ser gets a sip message : ERROR: receive_msg: no mem for sip_msg (and ser doesn't work and I can't have phone call) The probleme comes from the script ser.cfg or from mysql ? Thanks Gwen # ----------- global configuration parameters ------------------------ debug=1 fork=yes log_stderror=yes memlog=0 sip_warning=yes listen=10.0.1.139 listen=127.0.0.1 check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) fifo="/tmp/ser_fifo" port=5060 children=4 alias="arwen-tech.fr" alias="10.0.1.139" # ------------------ module loading ---------------------------------- 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" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 1) modparam("usrloc", "db_url", "mysql://ser:heslo@localhost/ser") # -- rr params -- modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- route{ 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; }; record_route(); if (loose_route()) { t_relay(); break; }; if (uri == myself) { if (method=="REGISTER") { save("location"); sl_send_reply("200","REGISTER OK"); break; }; if (!lookup("aliases")) { log(1, "ALIASES FAILED\n"); }; if (lookup("location")) { log(1, "USER FOUND\n"); if (!t_relay()) { sl_reply_error(); }; } else { log(1, "USER NOT FOUND\n"); sl_send_reply("404", "User not found"); break; }; } else { log(1, "OUT REALM\n"); t_relay(); break; }; }
