Hi
i m getting a problem while reading from MQ stage

My queue length is 8000
max message limit 2500000
i m putting 70,000 records of datasize 2678. but while reading with options

1)destructive read
2) commit / rollback only end of the job
checked

i was getting the error
" MQ read failed get message from Queue reason code 2024"

but for the same queue and same options if i reading the message of datasize 769, no error is coming

help me to solve this error.

(also i get to know that there is MQCMIT command to solve this , if so then how to put this command in MQ stage)
