We are using a DPT Smart Raid IV Card, PM3334UW on a RAID5 to run a news
server. Although the CPU percentage is not too high the SCSI disks can
hammer quite violently!
The problem that is occuring is that in the /var/log/messages file (and
on the console) we are getting the following errors:

Also the news server is very slow at collating the headers before
downloading them!!
Can anyone help??
Thanks in advance for any help
