sometimes i see following messages with FreeBSD-5.3, ahc driver and an 
easyraid ex system. We have two identical boxes one connected to another 
system has no problem. The problematic error messages occur when 
berkeley-db files are massaged by cyrus imap server.

I cannot believe there is a media error on an raid 5 system that is not 
announced at the control panel of the raid box.
