Okay, so I'm pretty sure not ending the job as instructed (or maybe not ending it at all) is causing me problems.
I made a change, and now I want to start the web server again. I'm using the following command in QSH:
node /mydirectory/node/sample.jsServer running at http://mysystem:8888
events.js:72
throw er; // Unhandled 'error' event
^
Error: listen EADDRINUSE
at errnoException (net.js:904:11)
at Server._listen2 (net.js:1042:14)

at net.js:1146:9
at asyncCallback (dns.js:68:16)
at Object.onanswer [as oncomplete] (dns.js:121:9)
$
I did a WRKACTJOB, but I can't identify the job.
Any ideas?
Thanks,

Crap. Scratch what I said about bash. I just remembered I've had race condition issues with it when exiting the Node.js REPL. Instead use
zsh(n1) from perzl (if you go this route).
Here are the install instructions for zsh (reference the article first to learn how to install the base shell scripts):
$ cd /QOpenSys/download
$ ./wwwperzl.sh aix61 wget zsh-5.0.5
$ ./wwwperzl.sh aix61 rpm zsh-5.0.5
n1 http://www.perzl.org/aix/index.php?n=Main.Zsh

I don't have an answer for QSH but can offer a significantly better--
alternative...
In this article** I describe how to install Git from perzl.org. The
same can be done to install bash (bourne again shell). Then you
should run STRTCPSVR *SSHD to start ssh on your IBM i. Then from your
laptop run "ssh ibmiprofile@ibmi_ip_address" to log into your IBM i.
And once logged in run "bash" and that will put you in a bash shell.
Or a shorter option would be to skip bash and only do STRTCPSVR *SSHD
and use the default Korn shell that comes with IBM i. In this option
you'd still use something like putty to create an ssh connection to your IBM i.
Then once in putty you can use Ctrl+C to end a node server.

My managers have given me the green light to explore node on the IBM
i (7.1).
I'm following the IBM developerWorks getting started page at:
https://www.ibm.com/developerworks/ibmi/library/i-native-js-app-ibmi-with-nodejs/.
The section of the page called "Create a web application using
Node.js" has instructions for developing a hello world web server. I
was able to get the hello world web server to run successfully:
* I created the sample.js file
* I put the sample.js file in the IFS
* I started a qshell session
* I executed the command "node /mydirectory/sample.js".
* I confirmed the web server was running by pointing my browser to
the URL and seeing the hello world message.
Here's where I got a little confused. The developerWorks page says:
"To end the web server job, you can press the Esc key within the QSH
session and select option 2 to work with the current jobs. Next, end
the job running the node program with option 4 as shown in Figure 6."
While still in the qshell session, I pressed the escape key on my
keyboard, but I did not get any options at all. I did not see a way
to follow these instructions for ending the job. I used F3 to exit
the qshell session. I pointed my browser to the URL, and it returned
the standard browser message saying the page was not available.
If a node web server is started in a qshell session, is it okay to
end the web server by simply stopping the qshell session?
Why did I not see any options when I pressed the escape key while in
the qshell session?
