Dear Greg,

Thank you for your reply. I noticed most of the futex changes between 4.9.233 to 4.9.279 is related to Priority Inheritance that comes in to use in the Real time kernel. But I am using the 4.9.232 Normal Kernel.

I do not know what a "4.9.232 Normal Kernel" is.

That's the reason I posted futex crash to the mailing list for input. is the race between futex_wait() thread and futex_wake() threads leading to NULL pointer crash? any input in that direction?

Again, please try the latest 4.9.y kernel release, we do not support older releases for obvious reasons.

thanks,
