hi,
I want to create task to perform monitoring the other task, so I wrote the following.
(*I reuse the code 'Can response and bootloader demo' in mcusw)

But, I run this code, slave threads are executed only a few times and stopped.
If delete Task_stat() code, That code is running successfully.
When I read this page(https://e2e.ti.com/support/legacy_forums/embedded/tirtos/f/355/t/572860), I think, Task_stat() function doesn't seemed to be the cause.
(Thread perform so small task, so STACK_SIZE is not the cause, too)
Thanks to regard.
