contiki timer

[apurva1992]

Hi,

I am using contiki-6lbr on my CC1310 custom board. In my application code, I periodically(every 5 second) perform an action. Code is something like below:

PROCESS_THREAD(udp_client_process, ev, data)
{
PROCESS_BEGIN();
etimer_set(&et_periodic, 5 * CLOCK_SECOND);
// Initialization code

while(1)
{

    PROCESS_YIELD();

    if(ev == PROCESS_EVENT_TIMER && data == &et_periodic)
    {
        //Perform some action
        //PRINTF statements
    }
}

}

Code is running perfectly fine for initial few days. After few days of non-stop working, code behaves weirdly and doesn't enter if condition of et_periodic timer. The code is still working as few other threads are still printing the logs. It seems that Contiki timer service thread is hanging after few days. However, I am not able to figure out the root cause. Any leads would be highly appreciated.

Thank you!
