Hi Subashree- This is a minor issue that has been fixed since 5.15.5 (recommend upgrading to 5.18.1) that is usually caused by consumers closing or rejecting messages.
Check the ‘dispatchedCount’ and see if it is noticeably higher than the dequeueCount. If so, your consumers are probably closing or rejecting messages that have been prefetched.
