Have you ever heard about or experienced performance degrading on E3 type
LC of GSR when a vast amount of packet which was being flooded to LC was
being dropped by Null route or Remote Triggered Black-hole? 

In this situation, our GSR produced a following error log.

SLOT 5:Feb 10 09:37:47: %SYS-3-CPUHOG: Task ran for 2644 msec (15/0),
process = CEF process, PC = 40DAD40C.

IOS : 12.0(25)S1
