[Serusers] serweb ctd

Hi, Im trying to use CTD from serweb 0.9.4 (as well as directly by executing ctd.sh with arguments) and it always returns me 503 Service Unavailable (my SER distro is 0.9.6). /var/log/serweb only shows this May 12 22:02:26 serweb [debug] Html form was not assigned to APU apu_aliases3. Useing default. May 12 22:02:26 serweb [debug] Html form was not assigned to APU apu_acl4. Useing default. May 12 22:02:30 serweb [debug] Html form was not assigned to APU apu_aliases3. Useing default. May 12 22:02:30 serweb [debug] Html form was not assigned to APU apu_acl4. Useing default. May 12 22:04:00 serweb [debug] Html form was not assigned to APU apu_aliases3. Useing default. May 12 22:04:00 serweb [debug] Html form was not assigned to APU apu_acl4. Useing default. ( What does that mean, by the way?? ) /var/log/messages would display an error like the following May 12 22:04:26 sip /usr/local/sbin/ser[18155]: ERROR: udp_send: sendto(sock,0x284bdc18,528,0,0x284bd210,16): Host is down(64) May 12 22:04:26 sip /usr/local/sbin/ser[18155]: msg_send: ERROR: udp_send failed May 12 22:04:26 sip /usr/local/sbin/ser[18155]: Warning: run_failure_handlers: no UAC support (0, 256) May 12 22:08:18 sip /usr/local/sbin/ser[18155]: ERROR: udp_send: sendto(sock,0x284bdc18,530,0,0x284bd210,16): Host is down(64) May 12 22:08:18 sip /usr/local/sbin/ser[18155]: msg_send: ERROR: udp_send failed May 12 22:08:18 sip /usr/local/sbin/ser[18155]: Warning: run_failure_handlers: no UAC support (0, 256) May 12 22:10:27 sip /usr/local/sbin/ser[18155]: Warning: run_failure_handlers: no UAC support (0, 256) May 12 22:11:16 sip /usr/local/sbin/ser[18155]: ERROR: udp_send: sendto(sock,0x284bdc18,485,0,0x284bd210,16): Host is down(64) May 12 22:11:16 sip /usr/local/sbin/ser[18155]: msg_send: ERROR: udp_send failed May 12 22:11:16 sip /usr/local/sbin/ser[18155]: Warning: run_failure_handlers: no UAC support (0, 256) May 12 22:12:03 sip /usr/local/sbin/ser[18155]: ERROR: udp_send: sendto(sock,0x284bdc18,485,0,0x284bd210,16): Host is down(64) May 12 22:12:03 sip /usr/local/sbin/ser[18155]: msg_send: ERROR: udp_send failed May 12 22:12:03 sip /usr/local/sbin/ser[18155]: Warning: run_failure_handlers: no UAC support (0, 256) and ngrep does not catch any INVITEs or REFERs. Im using eyeBeam to test this functionality. Does anyone have an idea what could be wrong?? Thanx in advance, Andrey.
