At this volume I would treat this as a warning but not a critical issue.
Inter-APIC messages get retransmitted in case of an error, but the
checksum circuit is not sophisticated -- a double-bit error might pass
unnoticed leading to a system unstability under certain conditions. At
such a low volume of errors double-bit ones are not likely to happen.
It's the first report of APIC errors on a P5 system I have seen, so it's
probably not a result of a bad motherboard design. I'd recommend to check
if the system doesn't get overheated. You may also be unlucky to have a
faulty board.
