I prefer using the STRDBG option.  I used STRISDB a long time ago, but I
don't remember how to use it, so I'll explain this using STRDBG.

IMPORTANT:  Before the problem occurs next, compile the RPGIII program
with OPTION(*SRCDBG).  (or if it's ILE, use DBGVIEW(*LIST))

Then, wait for the problem to happen again.  When it does sign on to a
different 5250 session, and do the following:

a) Set up your library list & current library the same as the offending
job.  This is important, since it needs to be able to find the same
program objects as the offending job.

b) Use WRKACTJOB to find the offending job.  Choose option 5 to display
the job.  At the top of the screen will be the job's name/user/number.  At
the command line at the bottom, type the following:  (Note that the order
of the fields is the exact opposite of what's at the top of the screen!)
   STRSRVJOB JOB(number/user/name)

c) Start the debugger with (leave off the "OPMSRC" bit if this is an ILE
program):
   STRDBG PGM(MYPGM) UPDPROD(*YES) OPMSRC(*YES)

d) The program's source should display on the screen.  Press F10 to step
through the program, line by line.   You can move the cursor to a variable
and press F11 to display the variable's value, or type "eval
VARIABLENAME" to see it's contents.

Hopefully, by watching it run in that manner, you'll be able to see what
it's stuck on / where it's looping.
