READ_DMA and WRITE_DMA errors usually indicate that your disk has bad
sectors or has become broken, but you have so many of them on multiple
drives (ad4, ad8, ad10), which might mean your disk controller is dying
or you have really bad cabling in the machine.
You might try using something like
# dd if=/dev/ad8 of=/dev/null bs=1m
to see if you can reliably provoke errors on the same part of the disk -
if not, there is certainly a problem with the controller or cabling; if
yes, it can also be a disk problem.
In any case, it looks like your problem is not related to any file
