I have a task to change the backend database of kamailio to mongodb. I have updated the DBURL to a valid URL of mongodb. Kamailio startup successfully firsttime when i insert some documents into the version collection. But after a user registed into kamailio, a location collection will be created. In this case i stop kamailio and try to start kamailio again, kamailio failed to startup. The log is: Nov 3 18:53:38 kamailio-1 ./kamailio[40735]: DEBUG: db_mongodb [mongodb_dbase.c:349]: db_mongodb_get_columns(): 20 columns returned from the query Nov 3 18:53:38 kamailio-1
