Coap Message is missed.

[wertyac]

If I use java coapclient to put the coap message to the emqtt. At the first time, it is OK and work well. However, after 5 mins, if I put the message again, EMQ can't receive the Coap message. I catch up the eth package in my desktop. It seems my java coapclient has sent the packages. And I also use tcpdump to capture the package in the EMQ server. I find the package arrived.

What is the emqttd version? What is your java coap client? californium?
