[Users] pdt problem

Dear list members, I've a problem trying to get pdt module working. These are the log I get with debug=9. pdt_print_tree: [sip.mydomain.com] pdt_print_node: [2] [proxy01.sipphone.com] pdt_print_node: [2393] [other.host.at.domain.com] pdt_print_node: [51] [my.host.at.domain.com] PDT:pdt_sync_cache: ... PDT:pdt_sync_cache: sync op[1]=1... prefix alredy allocated pdt_add_to_tree internal error! PDT:pdt_sync_cache: Error to insert into tree PDT:prefix2domain: cannot update the cache I'm working with openser 1.1.0-notls, and pdt.c version "v 1.8 2006/07/03 15:26:17 miconda Exp". MySQL description of pdt table is: +---------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------+--------------+------+-----+---------+-------+ | sdomain | varchar(255) | NO | PRI | NULL | | | prefix | varchar(32) | NO | PRI | NULL | | | domain | varchar(255) | NO | | NULL | | +---------+--------------+------+-----+---------+-------+ but the association sdomain,prefix,domain seems to be correct, as the pdt_print log lines report. Strange behaviour also occurs when I try to list from fifo the table every two times once I get: host:~# openserctl fifo pdt_list database engine 'MYSQL' loaded Control engine 'FIFO' loaded entering fifo_cmd pdt_list 400 pdt_fifo_list - domain not found FIFO command was: :pdt_list:openser_receiver_25901 while the second time openserctl hangs until I kill it with ctrl+c. Any suggestion will be helpful, thanks Francesco Castellano
