This sounds like it could possibly be a hardware problem to me, especially as it has only recently started happening. Can you run (say) Memtest86 overnight on the machine to see if that finds any issues? If that finds nothing, can you please show an example of these corrupted headers, and also the differences seen between the image on disk and the corrupted image that is served? Lastly, you could try upgrading to 7.2 and seeing if that resolves your issue - especlially as 7.0-RELEASE is no longer supported. http://www.freebsd.org/cgi/query-pr.cgi?pr=140876
