Description (partial)

ASR1K microde crash with either of the following errors

This issue ONLY affects on ASR1002x and ASR1K RP2/ESP100 based platforms
running 15.2(4)S, 15.3(1)S, 15.3(2)S, 15.3(3)S, and 15.4(1)S based images.

This issue can occur on platforms with scaled sub-interface or broadband
session configurations when the number of sub-interfaces or sessions on a
interface is reduced from > 4000 to less than 4000 and moderate to heavy

count is reduced.  If the the ASR1K is operating below this threshold or
above this threshold this issue is not seen.
