Problem or use case

Does it mean that the processing is too slow?i just put the message in ringbuffer(disruptor) ,thanks for help

Preferred solution or suggestions

We would need more information to go on to have a better idea but when sending as QoS 0, your design and code should plan for dropped messages from time to time.

Messages can also be dropped because of system contention, network issues etc..

Can you reproduce the message being dropped? If so, we might be able to provide some advice or insight.

Let us know.

Hi @liulongblog - I haven't heard back. Let me know if you still need help with this issue. Otherwise I'll close out the issue sometime soon.

Best, HiveMQ
