Cisco Cisco ASR 5700 Guide De Dépannage

Why does a crash that appears to be the same as already seen crashes get listed separately in
the crash list?

Analyzing the following two sessmgr process crashes, one might conclude they are the same and
wonder why the system has listed them separately in the crash list. On close observation, note
that there is a slight difference in 

 in the left most column of the show crash number

X output, which is the point in the code where the function on that same line calls the function
listed above i

t (

 in this example).
