In our project we using multiple interrupts like External interrupt, Timer, Serial Interrupts. In very rare case, controller gets completely freeze. Our Project is more sensitive and health based so its more important to ensure the reliability.

Kindly guide us to avoid freeze issue. Also kindly tell what are the possible reasons may besides these freeze issue

I would bet on a hardfault.
Or a lockup, when such a fault occurs in a fault handler.

As almost, the firmware.

You can attempt to provoke such an occurence in debug mode, or try to attach with the debugger to the "running" system when it occured.
