I have now went back to 4.13.16 as a test and it too is exhibiting the same behaviour. I think I have chased enough kernels for now. If there is anything else you need, please let me know. Thank you for your help in this matter. It takes approximately 283 seconds before the first error message popped up on the "aacraid: Host adapter abort request".

The server ran fine in older version. My apologies as I lost the exact version, but it never had any errors like this version. Now when ever I try to copy files to the RAID 5 drive, or untar a file, I get these errors now after a few MB's of written data.

I loaded in Debian9.4.0 and it only briefly showed this error once. But appears to be much more resilient and appears to work fine.
