I see this ocasionally on one of my CentOS 6.3 x64 systems:

Any thoughts on the cause? The system has 16GB of RAM, and whenever checked, there is no swap usage. Is this a memory error (bad RAM)?

I have the same problem on a Dell PE R720 with 16GB of RAM doing lots of networking. It's a file server. It was discussed on the dell-poweredge mailing list last week linux-poweredge@dell.com
The conclusion was that it was harmless but for a discussion and possible workaround see https://bugzilla.redhat.com/show_bug.cgi?id=770545#c16
Hope this helps,
*VERY* helpful, thanks!

Tim. Mark,
For another discussion of this bug see:
https://bugzilla.redhat.com/show_bug.cgi?id=713546
Again the conclusion seems to be that it's harmless, just some lost network packets which are then re-transmitted.
Should be fixed for 6.4 ;-)
