Subject: Strange assert failure, should I be worried?

Hi all.

Our application was reading from a BLOB stream, and allegedly something 
went wrong during the transaction (which is why we're seeing rollback 
here.)  We retry in such an event but apparently three failures in a row 
must have occurred, in which case we give up.  What baffles me the most 
is that I can't see any error with what's actually being displayed 
on-screen -- the data is all correct.

So should I be worried about this kind of error?  It's the first time 
I've ever seen one, and viewing the same data over and over doesn't seem 
to reproduce the problem.
