hi We are going to use "vppctl ping " to detect whether the device is reacehable, but we have some problem below :
we have above 50 service to do "vppctl ping 100.100.0.x repeat 1 table-id x " detect different devices, each service exec this command per 5 second, after 3~4 days, all vppctl ping service hang on, we use gdb to debug , vppctl are hang on below point at src\vppinfra\socket.c: clib_socket_init ================================== 416 if (addr.sa.sa_family == PF_INET) (gdb) 419 if (s->flags & CLIB_SOCKET_F_IS_SERVER) (gdb) 497 if ((s->flags & CLIB_SOCKET_F_NON_BLOCKING_CONNECT) (gdb) 505 if (connect (s->fd, &addr.sa, addr_len) < 0 ================================== it may cause some error on vpp socket , when vppctl connect to vpp many times. our vpp version is below, ===================================== Version: v19.08.1-229~g1517d5e72-dirty Compiled by: root Compile host: i-qvoo7mp3 Compile date: Fri Nov 1 20:53:55 CST 2019 Compile location: /root/ws/vpp Compiler: GCC 7.5.0 Current PID: 4652 ===================================== Linux version is below: Linux version 4.15.0-112-generic (buildd@lcy01-amd64-027) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 On the other hander, Is any other better method to do network health detection , like one-arm-echo bfd? because we may detect the device that not support bfd.
