With addr2line I found that it is zephyr/kernel/timeout.c 56 but it says nothing to explain what I have to fix. all threads have sufficient stack size. randomlyen-USTelligent Community 13Thu, 18 Jul 2024 22:05:58 GMThttps://devzone.nordicsemi.com/thread/494670?ContentTypeID=1Thu, 18 Jul 2024 22:05:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:53c3b04b-c7d6-4f2c-92bd-e62bb9870b30trampas<p>This often happens if you have exceeded the stack space allocated to a thread in Zephyr.&nbsp; Specifically you overflow the stack and it can cause random crashes in random places.&nbsp;<br /><br />I have also seen when I used certain sizes of stack, it would place the stack in one memory location and the system would crash.&nbsp; I could not find what the system was doing in that memory location, but we avoided it and marked it up to a random Zephyr/Nordic bug.&nbsp; It was on our list to go back and root cause.&nbsp;</p><div style="clear:both;"></div>
