ASR9K LC Crash

[Frank Patzig]

Hello,

i have in ASR9K a  LC A9K-8T-E. The LC reboot:

LC/0/2/CPU0: pfm_node_lc[295]: %PLATFORM-NP-0-HW_DOUBLE_ECC_ERROR : Set|prm_server_tr[159827]|0x1008004|NP DOUBLE ECC ERROR, NP=4, memId=19, subMemId=0x1

Is thies a bug ?

Have you fixed this issue? Is there any explaination

 - This is a hardware problem on the Network Processing Card; you should have it replaced.

Thanks for your response.

But i have a another samilar issue before.Cisco tac told me as below:
PID: A9K-8T-L

Error log:pfm_node_lc[290]: %PLATFORM-NP-0-HW_DOUBLE_ECC_ERROR : Set|prm_server_tr[155731]|Network Processor Unit(0x1008004)|NP DOUBLE ECC ERROR, NP=4, memId=18, subMemId=0x2

For the NP double ECC error, we could monitor it for two days. We could replace it if it happened in a short period.

but it's working well now, So I am in the process of judging whether there is a more accurate judgment.Maybe as TAC said, we will replace it if it comes again
