Description (partial)


Under typical operations, a XR based GSR PE router may encounter a kernel RP
crash which results in switchover or reload of the entire node.


So far one-time occurrence started with Active slot9 crashing due to a
parity memory error. Slot8 immediately took over and in  5 seconds later, 
crashed as well. Initial analysis points to memory corruption in the kernel code.
