Hello,
I've submitted https://github.com/kamailio/kamailio/pull/1932 to address
this problem.
I believe this is unnoticed if db_mongodb is already being used by some
module because mongoc driver would be initialized for each process.
The patch was tested in our testbed and it's working fine now.
Regards
