### Description Try to fill carrierroute with routing data and test result with `kamcmd`, but the rpc command never gives a result.
### Troubleshooting
#### Reproduction
``` /* ----- ctl params -------------------------------------------------------- */ modparam("ctl", "binrpc", "unix:/var/run/kamailio/kamailio_ctl") modparam("ctl", "mode", 0660)
/* ----- carrierroute params ----------------------------------------------- */ modparam("carrierroute", "config_source", "db") modparam("carrierroute", "db_url", "EXTERN_READ_DBURL") modparam("carrierroute", "fetch_rows", 2000) modparam("carrierroute", "db_load_description", 1) modparam("carrierroute", "match_mode", 10) modparam("carrierroute", "avoid_failed_destinations", 1) ```
Kamailio is running with the following parameters: ``` /usr/local/sbin/kamailio -u kamailio -g kamailio -m 512 -M 20 -n 16 ```
Fill carrierroute table with 110 Routes, do a routes reload and than try to get the routes dumped.
`kamcmd cr.reload_routes` and after that issue `kamcmd cr.dump_routes`, which hangs and don't return a result.
#### Log Messages
``` nothing regarding carrierroute in the log ```
