Hmm, i don't think this file is create at all in my build at all. I can't see why CentOS 8 picks it up. Can you verify it exists in your `build_folder/utils/kamctl/mongodb`?
There is this in in the old Makefiles https://github.com/xkaraman/kamailio/blob/6883143c3bd61c72fd738a2cef24bee472... , that is producing it. still trying to figure what it does exactly!
