Child process failed, exited with error number 1

I’m not able to start :
lev@lev-Precision-M4800:~/vmachines/ubuntu$ mongod -f setup/rs1_linux.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3501
ERROR: child process failed, exited with error number 1
To see additional information in this output, start without the “–fork” option.

Are you running this on vagrant box or your os
It says address in use
Any other mongod running on same port/address?

No, I don’t have any running copies of mongod in vagrant image…

Please double check
ps -ef|grep mongo

kill all mongods and start fresh
