CHGSPLFA problem maybe link to V5R1

Hello all,

I have an intermitent problem that is occuring at too of my sites that have 
recently migrated to V5R1. I will try to explain the situation:

- An rpg program generate a spool file. Before finishing, the same rpg program 
call QCMDEXC to execute a CHGSPLFA over the open spool file (we want to change 
the form type depending on some values). The command string looks like this:
CHGSPLFA FILE(RPGPRTF) SPLNBR(*LAST) FORMTYPE(NONSTD).

Most of the time, it works fine, but occasionnaly, I get the message CPF3303 
(File RPGPRTF not found in job //*). One funny thing I noticed is that 
normally, in the message, you see the job id (number/user/device) in the body 
of the message. But when my problem occurs, the job ID is //*.

Does anyone else has that kind of problem?

Any suggestion?
