Losing cloud connection, Thread CoAP Cloud example (SDK 0.11.0)

Dear Thread-experts,

I have troubles with your Thread CoAP Cloud example. I am using:

Thread SDK V0.11.0
Border Router V0.11.0, ethernet (not Wi-Fi)
cloud_coap_client example, adapted that I send more data (buffer size =256bytes)
Eclipse
Preview DVK, V0.9.0

I observe that after a while (sometimes day, sometimes minutes), no data are sent to the cloud. I debugged and my FW is running find and I don't get any errors (function otCoapSendRequest() is executed without error). However, the data is not visible in the cloud. The only way to recover it is: erasing the FW on the Border Router Network-Co-Processor-Thread-Module (Preview DVK). After erasing and reprogramming the DVK with the NCP, I can send data again for a certain time, until it brakes down again.

What I have observed is: when I send only 64bytes (insted of 256bytes): it tends to run more stable (some samples are missing, but the system is recovering itself).

I send the 256bytes every 6 minutes.

How can I debug that issue in more detail?

Thank you, Reto

The OpenThread source code was fixed and Jonathan accepted it (see #2424 via #2435.)
