I'd like to know what's in raidPtrs[0] (or raidPtrs[1] or whatever
number the RAID set is). In particular, knowing what's in the
raidPtrs[0].Queues structure might be useful.
The trick is to figure out why a getiobuf() call returned NULL, or
whether or not the diskqueuedata pool was exhausted...
Feel free to contact me off-line about this...
Later...
