You havn't said what the config file looks like, but I'm guessing your 
'sectors per stripe unit' (sectPerSU) value may be too high.  You also havn't 
said what RAID level you're running, the types of disks, the phase of the 
moon, etc. :)  More info is needed before I can provide useful suggestions...

Later...
