Program looping

[Peter.Colpaert@xxxxxxxxxxxx]

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.
