On QFX5100 and EX4600 switches, every time a MAC address is learned, some messages might be output to syslog and be repeated frequently. The logged messages have no impact on service traffic.

External-Title
QFX5100 reports false parity error messages like "soc_mem_array_sbusdma_read" & "soc_ser_correction: mem write".
Customer-Risk
minor
Release-Note
SDK can raise false alarms for parity error messages like "soc_mem_array_sbusdma_read" & "soc_ser_correction: mem write" on QFX5100.
Workaround-Provided
yes
Workaround
Reboot resolves the issue temporarily. Issue might come back later.
External-Description
1. Software Development Kit mistakenly believes existence of parity errors. This false reporting manifests itself via following log messages on the switch:
Feb 10 14:41:47.422 H01-387A-D25-250 feb1 _soc_mem_array_sbusdma_read: ING_FLEX_CTR_COUNTER_TABLE_5_X.ipipe0 failed(ERR)

2. The SW fix for this issue is in 14.1X53-D37 onwards
