This read-only Counter reports the number of times the hardware failed to successfully arbitrate between multiple requests to access the Ethernet interface's local memory, which the description notes would normally indicate a hardware problem. An admin seeing this counter rise would treat it, like the related DMA and parity error counters, as justification for hardware replacement rather than a software fix. For example, this counter climbing alongside cntdot3PICMemParityErrs on the same interface would strengthen the case for a failing memory component on that card.
