issue in taking backup of messages in MQ using dmpmqmsg

We faced a issue in production.A queue has curdepth of 176.but while taking backup,its showing only 170 messages . There is no uncommitted messages also.. why 6 messages are not getting backed up? enter image description here

Issued command:-

dmpmqmsg -m <qmname> -i <queuename> -f <filename>

enter image description here

When I checked using the amqsbcg sample program, I could see all 176 messages. 176 headers were there. There were no empty messages.

A couple of thoughts:

(1) From the time you issued the 'dis ql({qname})' command to you running the dmpmqmsg program, 6 messages could have been consumed by another program.

(2) Those 6 messages could be expired messages.

(3) Even though UNCOM has a value of 'NO', you can run the dspmqtrn program to see if there are any uncommitted messages:

Internally coordinated:

dspmqtrn -i -m {QMgrName}

Externally coordinated:

dspmqtrn -e -m {QMgrName}
