receiving message from QSYSOPR msgq

Hi list,

First I have to say that I am not well experienced with the way the i's
messaging system works. But digging around did not shine the light to me.

I have arranged some CL code for a batch job to bring the system to
restricted state and do a SAVSYS.
All working well, I can intercept the message which tells that the system
has reached restricted state, and continue to the save procedure.

This code works:

ENDSBS SBS(*ALL) +
OPTION(*IMMED) +
BCHTIMLMT(120)
WAIT:
RCVMSG MSGQ(QSYSOPR) +
MSGTYPE(*INFO) +
RMV(*NO) +
MSGID(&MSGID)
IF COND(&MSGID *NE 'CPF0968') +
THEN(DO)
DLYJOB DLY(20)
GOTO CMDLBL(WAIT)
ENDDO
/* And the SAVSYS goes on*/

But before the ENDSBS I need to send an other message to the MSGQ of
QSYSOPR. When I thus invoke for example:
SNDUSRMSG MSG(&MYMSG) +
MSGTYPE(*INFO) +
TOMSGQ(*SYSOPR)

And then the routine is no longer functioning. The WAIT loop then keeps
running until the BCHTIMLMT has expired.
So it seems to be caused by my sending of that before message to the msgq of
QSYSOPR. But I don't understand why, and also cannot find a good solution
for it.
This is driving me nuts. I must be doing something wrong, but what?

Thanks in advance,
Arco Simonse
