JunOS : Buffer management parity error detected in mpfe1, value 0, re-init the PFE

By | November 9, 2019

Encountering the following error in the logs of your Juniper device?

/kernel: Buffer management parity error detected in mpfe1, value 0x4001, re-init the PFE
/kernel: Buffer management parity error detected in mpfe1, value 0, re-init the PFE

This is most likely pointing toward defective hardware, more specifically memory issue.

If this message showed only once, you may stay on alert and monitor closely. If it repeated three times in the last two years, raise a JTAC case for RMA.

If you’ve encountered this message, and your device rebooted by itself, hang at boot with “PWR OK” status code and need to pull out the power cord(s) to get your device back online, you definitely need to take immediate action to replace your device.
