Hello Bogdan,

nice to see you again !

here the stuff :

[Thread debugging using libthread_db enabled]
Core was generated by `/opt/opensips/sbin/opensips -P
/opt/opensips/var/run/opensips.pid -m 256 -u sam'.
Program terminated with signal 8, Arithmetic exception.
#0  0x00007f26f086c513 in ds_select_dst (msg=0x80ebe8, set=<optimized out>,
alg=0, mode=<optimized out>,
    max_results=<optimized out>) at dispatch.c:1235
1235                i = (i+1)%(idx->nr-1);

(gdb) p i
$1 = 0

(gdb) p idx
$2 = (ds_set_p) 0x7f26dee90350

(gdb) l
1230
1231        i=ds_id;
1232        while ( idx->dlist[i].flags&(DS_INACTIVE_DST|DS_PROBING_DST) )
1233        {
1234            if(ds_use_default!=0)
1235                i = (i+1)%(idx->nr-1);
1236            else
1237                i = (i+1)%idx->nr;
1238            if(i==ds_id)
1239            {


I re-tested with a few modifications, like changing IPs in the dispatcher
list file, or into the routing logic ("do it simple like in the docs
examples"), the same problems still happens :/

here's the corefile if needed :

Best regards,
