The number of jobs spawned from my process doesn't seem to be any different whether I loop on the queue every second or every 60 seconds. I just see messages like this:
"Job 089269/QUSER/QSQSRVR used for SQL server mode processing."
And it uses the same handful of jobs (six in my case) but I am the only user on the LPAR. It may well be plenty more than that in a multi-user environment, but it certainly doesn't appear to be starting/stopping on each loop. So I still cannot really comprehend how it is killing the server.....yet.

Many thanks - you have done the donkey work for me :)
The documentation is pretty woeful....although probably better than mine!

I have never used xmltoolkit directly. Here I am just using the new

which I am sure uses xmltoolkit under the covers, but there is no
reference to an IPC value
at the level I am working with :(
The documentation is spread out between DeveloperWorks and YIPs.
Search the following page for "ipc":
http://tinyurl.com/nufv2gk
Here's an example of assigning a value to "ipc" and passing it as a
parameter to the iConn() function in Node.js:
var xt =
require("/QOpenSys/QIBM/ProdData/Node/os400/xstoolkit/lib/itoolkit");
var options = {
ipc : "/tmp/whatever"
};
var conn = new xt.iConn("*LOCAL", "USER", "PASSWORD", options);
Before you begin playing with "ipc" you might want to test the
hypothesis about your Node.js program starting and ending JOBS in a loop:
DSPLOG MSGID(CPF1124 CPF1164)
Monitor for JOB "start" and "end" messages. Fill in other DSPLOG
command parameters to limit the search if you know the JOB names.
You could set your queue wait time back to 5 seconds to do a stress test.
Tony Cairnes mused that the acronym "ipc" was derived from the Unix
command "ipcs", which displays a list of processes which are using
shared memory for inter-processes communications.
