I think I have a long running mongo script tanking my database, but I'm not sure. I was connected to the linux server via SSH and I ran the script like so:

mongo my_database my_script.js

It started chugging away, but it was taking too long, so I hit Ctrl-C and dropped back to the shell. I assumed the script was killed off, but now I'm seeing queries that it contained still running on the database.

How do I get a list of scripts the database is currently running and kill them? I know about db.currentOp and db.killOp, but the actual queries themselves are quick, I need to kill the script that's running them in a loop.

Ok, the query was tanking our database, so we just restarted the mongod service. Our other secondaries stepped up, which was good, but this is not the solution I was looking for. –  LoveMeSomeCode Mar 28 at 19:09

To find any running task with mongo in its name run:

ps -eo pid, command | grep mongo

Which should output you a list with the process ids and the commands currently being executed. When you identify which task you want to kill, grab that associated number (imagine that it's 582) and run:

kill -9 582

This will send a SIGKILL signal.

The SIGKILL signal is sent to a process to cause it to terminate immediately (kill). In contrast to SIGTERM and SIGINT, this signal cannot be caught or ignored, and the receiving process cannot perform any clean-up upon receiving this signal.
