When i use emqtt-bench pub -t "topic/1" -c 5 -w will report the error of the title, what's the reason

[2-ming]

Is the -w parameter used correctly?

[id]

the error in the title is most likely harmless

[2-ming]

When the number of connections is large, use the -w parameter, there will always be several such errors reported, and the number of messages published per second will be correspondingly less.
