Azure Sphere Runtime SIGKILL

Question

Hi,

When I run my program on Azure Sphere in debug mode, it shows this message and closes the debug:
Program terminated with signal SIGKILL, Killed.
The program no longer exists.

Any advise of why this is happening?

Hello @Mehrdadh ,

If your application uses too much memory, the Azure Sphere OS terminates it with a SIGKILL signal. For example, in the debugger you'll see the following:

Child terminated with signal = 0x9 (SIGKILL)

The SIGKILL signal also occurs if a high-level application fails to handle the SIGTERM request; see Lifecycle of an application for details.

Also, see Memory use in high-level applications

Hope this helps.
