Wondering if you have scheduled automatic media scans of all of the disks in the array? Perhaps you have a disk that is going bad causing the issue.
Something else that could be related, I was told by someone who had a Isilon storage system(fancy NAS box), who was having his WD disk drives hang on him on occasion, when this occured he had to physically remove the disk from the system and re plug it in. It was a firmware issue, I don't recall which WD drives he had, he eventually got a fixed firmware though. This was about a year ago.
I have media scans run once a week for about 7 hours on my 2 disk 3Ware systems (8006-2 controllers). For a 24 disk system you'll probably need to run it longer. (unless the newer controllers scan in parallel, the 8000 series seems to be serial).
I ran a couple 9650 series cards not too long ago, I think they were just two disk systems running RAID 1 (up to 8 disks, but only used 2). I've been using 3ware cards for about 8 years now and have not run into those types of errors you describe. Probably ran about 350 cards over the years, most of them in the 8000 series.
