Hello,
It looks to be more DNS oriented than Kannel, please try to ping your hostname before. Happy new year De : users [mailto:users-boun...@kannel.org] De la part de kabin mool Envoyé : lundi 1 janvier 2018 07:05 À : users@kannel.org Objet : PANIC error in Kannel Hi, I have recently used kannel 1.4.4 and getting this type of error regularly in my log. Any idea, in which case this error is generated and how can it be corrected. 2018-01-01 07:20:47 [6866] [9] ERROR: Error while gw_gethostbyname occurs. 2018-01-01 07:20:47 [6866] [9] ERROR: System error 1: Operation not permitted 2018-01-01 07:20:47 [6866] [9] ERROR: Couldn't find the IP number of `Happynewyearpapa.' 2018-01-01 07:20:47 [6866] [9] PANIC: gwlib/socket.c:571: udp_sendto: Assertion `octstr_len(addr) == sizeof(sa)' failed. Thanks, Kabin
