QFX5100s continuously generates parity errors and SBUS transaction errors.
The following parity Errors and SBUS Transaction Errors logs appear constantly:
fpc0 Parity error..
fpc0 Error in: SBUS transaction.
fpc0 Unit 0: soc_ser_correction: mem write ING_FLEX_CTR_OFFSET_TABLE_4.ipipe0[33311] failed: Invalid parameter

The switch is running 14.1X53-D30, which is now end of support.
The issue is resolved through PR1161821
Upgrade your switch to a supported version to mitigate this issue.
NOTE: Rebooting the switch will resolve the issue but this is a temporarily workaround since might come back later.
