RE: Program looping

Been there, done all that.

BTW, it's darn USER (singular) as this particular lady is the only one who can
get this program to loop.

We have tried monitoring her job, running it on our development system 5 at a
time, tracing through it top to bottom, but not a clue.

An additional issue is that (as I mentioned before) she doesn't have this
problem _every_ time she runs the program.

Before looking to OS/400 issues, or communications problems, look first to
the program -
as you cannot reproduce the error (darn users) try the following...

When the user is on and looping, issues a STRSRVJOB <number/user/job>
command,
then issue the appropriate start debug to your program (STRDBG or STRISDBG;
as people
have a different opinion on the term RPGIV, I leave the correct debugging
tool to you)

You can then issue break points and watch what is happening for this user

"If" you see nothing, make sure your PTF's are up to date (or for that
matter your OS).

After that, you are more into possible hardware/communications issues, and
may end up
getting outside help depending on how you are connected, comm lines,
routers, emulators,
and such.

Hello group,

We are experiencing a most annoying problem, what's more, an _intermittent_
problem (i.e. it doesn't occur always, nor for everyone) in an RPG IV
program.

One (and only one) of our users manages to get this program looping on the
production machine, and no matter what we tried on our development box, we
cannot reproduce this error.

The looping causes a CPU load of 90+ % for this user's job, and causes the
user's message queue to wrap, so that we can only see it when it's too late.
At
the time we notice the problem, the joblog is filled with one single error
message repeated over and over again (CPF5013 Cannot process subfile
request) to
which the system replies 'C'.

As we cannot reproduce the error, I was wondering whether any of you have
had
the same problem.

My guess is that it has something to do with the line failing at some point
(the
AS/400 is located here in Gent, Belgium and the user is located in South
Africa)
but we are not sure at all.

Thanks for any suggestions.
