On a VIPRION B4300 blade, VIPRION B2250 blade, or BIG-IP 10000-series appliance, messages similar to the following may be logged in the LTM log every 2 seconds: info bcm56xxd[25425]: 012c0016:6: _soc_xgs3_mem_dma: ING_SERVICE_COUNTER_TABLE_Y.ipipe0 failed(NAK) info bcm56xxd[7610]: 012c0016:6: _soc_xgs3_mem_dma: EGR_VINTF_COUNTER_TABLE_Y.epipe0 failed(NAK) info bcm56xxd[11548]: 012c0016:6: _soc_xgs3_mem_dma: EGR_SERVICE_COUNTER_TABLE_X.epipe0 failed(NAK) Similar errors also appear in the bcm56xxd log file.
Since these errors are reported for the interface that is used to retrieve stats from the Broadcom switch chip, they are not expected to impact the packet path/traffic passing.
This error is logged if an internal parity error is reported by the Broadcom switch chip when stats are read from the chip by BIG-IP.
To work around this issue, you can restart the bcm56xxd process on the affected appliance or blade. To do so, perform the following procedure: Impact of workaround: The BIG-IP system stops processing traffic. You should perform this operation only during a maintenance window or when the system is in a standby state. 1. Log in to the BIG-IP command line of the affected appliance or blade as the root user. 2. Run the following command: bigstart restart bcm56xxd.
