The ESTABLISHED sockets have a process at each end and they are communicating. Eventually the processes will invoke close(2) or shutdown(2) on the sockets and they will go away. You could also kill the processes and the exit(2) system call will close them.
When a socket completely closes, it will enter TIME_WAIT for awhile before it disappears. In your case you have two processes talking on the same host. Usually there would be two different hosts with a network connecting them. It is possible for packets to have been lost in transit. Such packets could arrive late, even after the socket has closed. If a packet arrives for a socket in TIME_WAIT, it is discarded. If you somehow discarded a socket in TIME_WAIT, you lose that protection. The socket could be reused and it will freak when any lost packets from the previous connection arrive. TIME_WAIT sockets should not last very long.

SYNOPSIS
mongo [OPTIONS] [DB_ADDRESS] [FILE+]
DESCRIPTION
mongo is a JavaScript shell (with GNU readline capabilities). It supports interactive and non-interactive use. When used interactively,
JavaScript can be used to query the database or perform any other function normally available with SpiderMonkey. Database output is dis-
played in JSON format.
If JavaScript files are specified on the command line, the shell will run non-interactively, running each one in sequence and then exiting.
EXAMPLES
mongo start the shell, connecting to the server at localhost:27017 and using the test database
mongo foo
start the shell using the foo database at localhost:27017
mongo 192.169.0.5/foo
start the shell using the foo database at 192.169.0.5:27017
mongo 192.169.0.5:9999/foo
start the shell using the foo database at 192.169.0.5:9999
mongo script1.js script2.js script3.js
run three scripts and exit
OPTIONS
--shell
run the shell after executing files
--help show usage information
--host HOST
server to connect to (default HOST=localhost)
--port PORT
port to connect to (default PORT=27017)
--nodb do not connect to mongod
