Hello Everyone,

Need your inputs on finding the possible cause for amqsmon returning a high GetFailCount.
amsmon returned the below output
QMinDepth:QMaxDepth:PutCount:GetCount: GetFailCount: BrowseCount: BrowseFailCount:
0 51 2486 2486 2416 4910 4715
0 54 2285 2285 2214 4513 4176
0 88 1020 1020 893 1929 1702

Location: US: west coast, almost. Otherwise, enroute.

The usual culprit is a RC 2033 no message available. Could also be queue attribute get(inhibited). Take a look at the IBM documentation for MQGET reason codes to see the small fleet of possible get failures. What errors did the app(s) catch?

Queue depth is more than 15000 when we have the GetFailCount in the range of 5k. Could there be any other reason?

Uncommitted messages count toward queue depth but are unavailable for GET could be one reason...

Bad programming? In a loop getting messages but forgot to clear MsgId and/or CorrelId before issuing the next MQGET.
