Hi Pavel,

What program are you using? Can you take a look at this github issue and see if it is relevant to what you are looking for?:

Hi Karen, my project is a big one so i can't post the code. Uses multiple Timers, a few LowPowerTimer, 2x UARTSerial, 2x CAN, 2x I2C, SPI , when compiled FW size : 170kb so as you can see i don't know where to start looking.

I had a quick look into that issue and it was fixed. So how do I know if destructors are ok in OS? It would be nice to know what "things" can cause this problem

I have enabled debugging with OpenLog and interesting things it that processor uptime (measured with RTC) is only as follow (in seconds): 32890 32891 32889 32891 32889

and always after that period i get previous error
