Edit: I do not know wether I was simply wrong with my answer or if the behavior of bind_ip was changed, but it is possible to bind to multiple, distinct IPs
bind_ip:127.0.0.1,10.0.0.1,8.8.8.8
So, most likely, one of the IP addresses mongod was assigned to bind to did not exist on the machine in question.
You can bind mongod only to one IP, with 0.0.0.0 being the alias for “listen on all available network interfaces”.
So either use
bind_ip=127.0.0.1
to listen to the loop back interface or
bind_ip=<someIP>
to listen to that IP only or
bind_ip=0.0.0.0
to listen to all available IPs on the system.
If you need to listen to several specific IPs, it is very likely that your system design is somehow screwed.
