We have a Juniper MPC4E-3D-32XGE-SFPP that has been performing fine for the last two years but is starting to generate alarm messages in the logs:
This error comes up every minute or so:
fpc10 Error: /fpc/10/pfe/0/cm/0/PQ3_Chip/0/CMERROR_PQ3_DDR_1_BIT_MINOR (0x160001), scope: board, category: memory, severity: minor, module: PQ3 Chip, type: PQ3 DDR single bit minor error
This error comes up frequently, between 2 to 15 minutes apart:
chassisd: CHASSISD_FPC_ASIC_ERROR: <FPC 10> ASIC Error detected errorno 0x00160001 (null)
I'm guessing that the errors are related, but I can't find any information on the second message. Has anyone see this before?
