`redis` database is clean, just started the first time. I tried change -M and -m options, it does not matter.
I found the issue raised when Kamailio try to load the whole table. ``` 0(54469) DEBUG: db_redis [redis_dbase.c:2319]: db_redis_query(): querying prefix (table) 'rtpengine' 0(54469) DEBUG: db_redis [redis_dbase.c:2370]: db_redis_query(): no columns given to build query keys, falling back to full table scan ``` If I specify a table key, then Kamailio start properly.
