[SR-Users] kamailio does not start with db_mongdb and usrloc

[Stephane Focant]

Hello,
I have an issue when I try to use kamailio 5.1 with usrloc and db_mongdb
modules.
When I try to start kamailio, I get the following error:

In mongoDB, I have the collection "version" in the db kamailio, and the
entries needed for usrloc (location and location_attrs):
sre_location:PRIMARY> use kamailio
switched to db kamailio
sre_location:PRIMARY> db.getCollection("version").find()
{ "_id" : ObjectId("5a8ec43c601b262bef82a595"), "table_name" : "location",
"table_version" : 9 }
{ "_id" : ObjectId("5a8edb72a3ec40427577b8d0"), "table_name" :
"location_attrs", "table_version" : 1 }


And logs in mongo show the following info when kamailio starts:

2018-02-22T17:13:02.604+0100 I NETWORK  [conn90] received client metadata

I probably miss something: it is not clear to me why kamailio is not able
to retrieve the value of table_version for the table_name location. Any
idea would be very welcome !

I use mongo-c-driver 1.9.2 and mongodb 3.6

Thank you.
