Symptoms: A line card or port adapter may generate SYS-6-STACKLOW error messages and reload
because of a software forced crash. The crashinfo file shows that the crash is caused by the CEF
Scanner process that is related to recursive calls:

The output of the show cef events command for the line card or port adapter shows that a CPU hog
condition occurs after the CEF Scanner process:
...
Process Scanner event loop enter
CPUHOG -1ms XDRtyp 8=control len=11 Hex:0F0000079C00FA00
CPUHOG 2044ms XDRtyp 8=control len=13 Hex:08000000038E2A541A01
