I have Linux machine red hat 7.2
because the dropping problem on eth1 interface
we perform the test according to red hat link - https://access.redhat.com/solutions/206223
finally we get the following results from crash tool
crash> sym 0xffffffff8152aa5b

please help me to understand the output from crash , what the meaning about the files path , dose this mean that problem is on the files ?
example from ifconfig about the dropping that increased every second:
