ESP32S3 usbnsh hang on ps command about nuttx

[w2016561536]

I met this kind of bug too. This bug could be triggered after some heavy load such as coremark.

@tmedicci @eren-terzioglu @fdcavalcanti please take a look

I met similar some time ago. In my case the default stack was configured to too small value. Setting default task stack to 4K fixed the issue. Here I see the stack is set to 8K, so that should not be an issue. Would be good to enable stack coloration to see the % of stack consumption.

Ups. Just checked the code and was confused by 002000 interpreting this as hex value, but found %06lu is code. So still can be default stack size issue

[pkarashchenko]

Maybe worth of changing %06lu to %6lu that will remove prefixed zeroes for decimal value...

Thanks, it's the same issue:

It won't hang if I increase the stack size for nsh.
