MQTT stops responding after fixed number of subscribe and publish

[Jawad]

Hi everyone,

I was having RAM overflowed with stack issues which were resolved using suggestions here. Now I am facing another issue. While running mqtt I can only do a fixed number (15) of mqtt publish or subscribe requests and then mqtt stops responding to received messages. I am suspecting this as a memory issue where stack pointer reaches an undefined location. Does anyone have any suggestion to debug such an issue while the project is running? Thanks a lot

Hi Jawad, I am not quite sure how you should debug this, but I will discuss this with the IoT SDK team and come back to you.

Thanks Bjorn, Just to add, the issue seems very similar to what is explained here i.e. memory leaking. Looking forward to your response

@jawad: I guess this has been answered in this question.

Hi Bjorn,

No, the issue is still there. Heap and stack doesnt seem to be the issue. MQTT is still failing after 15 transactions.

Thanks
