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
