Andre,
What were your SCSI errors ?
We have one system that has now run for five days without failure. Today we
will start to deconstruct this unit, any advice would be welcome.
We also ran five system over the weekend and all but the one, the IDE system,
failed.
These were:
A repeat of the passing system above, failed with
Bad blocks 135666304, inode 5142534
6 seconds later, Bad blocks 135666304, inode 5634466
then, panic ffs_blkfree: freeing free frag, this is on the /RAID partition.
Test run against an IDE disk, still running but slowly
Test run against a SCSI disk
Test run using a Symbios dual SCSI card,
Test running FreeBSD 3.0
Two of the above tests have got struck in iowait, for example.

Just a few minutes ago cron started to die with a signal 10, we don't think this
is relevant but...
