Yes, the log entries are truncated in the log, which is bad for the
CONDUIT products.  (Maybe a useful change would be to log the rightmost
portion of such a long product ID.)  

I was assuming differently, that the products that were dropped were not
the products on which the timeout occured.  I assumed this because I
have not heard other reports of dropped products on disconnects and thus
I assumed that the logic to resend a product that was not completely
sent was good.   I'm thinking that the problem lies in the ordering of
the products in the queue.  With the CONDUIT feed being broken up into
multiple connections, I'm wondering if that increases the liklihood of
products being ordered nonchronologically in the queue, resulting in
more dropped products.  This is why I asked if you had noticed dropped
products on other feeds besides CONDUIT.  Have you?
