Internal buffer too small on NCS520 (cisco N520-20G4Z-A)

[iman yousefi]

Hello everyone,

I recently found the following logs on some of our NCS520 devices:

1 - %IOSXE-1-PLATFORM: R0/0: kernel: nif: Internal buffer too small
2 - %IOSXE-1-PLATFORM: R0/0: kernel: nif: Invalid CPP Header info :: total_len (3489) / packet_len (13787)

Does anyone have any suggestions on how to resolve these issues?

  - Check software version being used on the NCS520 ; lookup the advisory release and consider upgrading; especially if you are on an older release (it could be related to bugs)
