Kamailio-5.2.1 - Issues in NDB_MONGODB module initialisation - sr-users

18 Apr 2019

Hello there,
I have NDB_MONGODB loaded in kamailio with following configurations:

*loadmodule "ndb_mongodb"*
*modparam("ndb_mongodb", "server",
"name=mgs1;uri='mongodb://mongodbserver:27017/proxyregistrar'")*

Kamailio breaks up on start up and prints the following messages:

*Apr 18 13:16:10.464 proxy-registrar[-]: DEBUG: <core>

NDB_MONGODB configuration is pretty simples and currently i'm not making
any mongodb operations, i'm just loading the module and trying to connect
against mongodb.

Any thoughts on this issue?

Thank you

Best regards
