mongodb: UnknownError assertion src/mongo/db/server_options_helpers.cpp:355

Question

I was running mongodb without any issues until now. I don't really know what happened, as don't remember doing nothing weird. Still, now I get the following error when I try to launch the mongo server.

$ mongod --config /usr/local/etc/mongod.conf

I've tried running mongo --repair too, but got the same error.

Answer 1

This is weird!

I'm on OSX, using iTerm where I've tried to run the above process. Once I've quite iTerm, and restarted it, the created shell could run the process without any problems.

It seems as the process could not stop previously. Before, I even tried running mongo to see if I can connect, but it failed.
