MCH3402 - Tried to refer - MQCONN

Hi

I get this problem everyday in  a batch job and it comes from a MQ
service program AMQZSTUB

---------------------

One strange thing is that the same error came from another program
(PGM1) but the first program continued (even though there was no
MONMSG for the program CALL)

I am not able to find out out when did I loose pointer for MQCONN in
AMQZSTUB... I did not see any escape messages coming from any
component bound to AMQZSTUB in this job...


thx
