Re: [SR-Users] Unable to start Kamailio with acc_json

Dear List, I have a problem with initializing acc_json. As soon as I try to load acc_json module, Kamailio fails to start. I get the following messages to log with debug 4 (non-related messages omitted): Jan  7 16:17:42 labkam2 kamailio[51089]: INFO: acc_json [acc_json_mod.c:99]: mod_init(): janson version : 2.9 Jan  7 16:17:43 labkam2 kamailio: ERROR: <core> [core/daemonize.c:303]: daemonize(): Main process exited before writing to pipe Running 'bt full' on coredump tells following: (gdb) bt full #0  strlen () at ../sysdeps/x86_64/strlen.S:106 No locals. #1  0x00007f086d0a69fd in mod_init () at acc_json_mod.c:120         __func__ = "mod_init" #2  0x000055f1699cc6a2 in init_mod (m=0x7f087c0983d0) at core/sr_module.c:897         __func__ = "init_mod" #3  0x000055f1699cca16 in init_modules () at core/sr_module.c:926         t = 0x29ceb62d         i = -1         __func__ = "init_modules" #4  0x000055f16989445a in main (argc=3, argv=0x7ffc56d94378) at main.c:2617         cfg_stream = 0x55f16beb0010         c = -1         r = 0         tmp = 0x7f087c9512e7 "__vdso_getcpu"         tmp_len = 32764         port = 1457078704         proto = 32520         options = 0x55f169c019f0 ":f:cm:M:dVIhEeb:l:L:n:vKrRDTN:W:w:t:u:g:P:G:SQ:O:a:A:x:X:Y:"         ret = -1         seed = 2201341167         rfd = 4         debug_save = 0         debug_flag = 0         dont_fork_cnt = 0         n_lst = 0x0         p = 0xf0b0ff <error: Cannot access memory at address 0xf0b0ff>         st = {st_dev = 19, st_ino = 306346, st_nlink = 2, st_mode = 16832, st_uid = 0, st_gid = 0, __pad0 = 0, st_rdev = 0, st_size = 80, st_blksize = 4096, st_blocks = 0, st_atim = {tv_sec = 1543318847, tv_nsec = 544329773}, st_mtim = {tv_sec = 1546870639,             tv_nsec = 902332400}, st_ctim = {tv_sec = 1546870639, tv_nsec = 902332400}, __glibc_reserved = {0, 0, 0}}         __func__ = "main" I have loaded "acc" module before loading "acc_json", are there any other mandatory prerequisites?
