Really? I guess it could be because we are using ZServer, but we notice that
when packing the box does nothing else. Its a twin 600 mhz cpu with 1 gig of
RAM so I would be surprised if the machine is the problem. Umm I would be
curious to know why this is a problem. Our db is around 1.5 gigs at the
moment. We just got a CorruptedTransactionError as well which is cool :(
