[CentOS] APIC error on Intel Atom CPU, CentOS 5.x

I am seeing ``APIC error on CPU3: 60(60)'' warnings from dmesg periodically on a CentOS 5.4 box, kernel 2.6.18-164.11.1.el5. The CPU is an Intel(R) Atom(TM) CPU 330 @ 1.60GHz. I am not a hardware type, and don't have a clue what this means.

This is occurring while an rsync-3.0.4 process is receiving data sent by a machine running rsync-3.0.7 (I just updated the CentOS box to rsync-3.0.7 since noticing that it was a bit dated). This is the only significant load on this machine at this time.

This machine has locked up requiring a hard reset twice while this rsync process has been running at night with no problems at other times.

Any suggestions?

Thanks.

Bill
