mongod --dbpath /Users/rahul/data/db command not working - mongodb

Question

I installed MongoDB on my PC. It was working perfectly, but suddenly it stopped working.
When I try to sudo mongod --dbpath /Users/rahul/data/db I get this:

Answer 1

Exit code 48 means the port is already in use, Check for any running mongod process and stop it to free the port.
And it is mentioned in the error log you posted
{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}
