>There are some known issues with some Novell drivers and with write caching drive controllers. How isolated is this case? Is it happening consistently or was it a one time occurance?

It seems like there may be a handful, less than 7, each week. But it seems random. today it didn't happen. yesterday there were 2. I can't get determine any relation between the rows either - (for example, if they both appeared in the same billing batch, or they were editted by the same user around the same time - there's got to be some method to the madness, but I guess if I could figure that out, I'd be able to solve the problem.)
