A ethernet 802.x packet is a struct of:

Packets are resent. The amount of packets is depending the size of the
receive window. If memory serve the receive window (where TCP send ACK)
can be till 8 kb.

I assume you use TCP. No need for additional check. I never have seen a
corrupt packet in TCP. Even not on radio networks where there is planty

AFAIK TCP already does CRC per packet so MD5 may be a bit expensive

Hello,
I'm writting a small C/S protocol. It includes sending/receiving
database records. Would you suggest to send and check a MD5 checksum?
May be it is OK to live with this overhead only upon database write
requests?

The only reason I can think about is that there is eather an exception

No I have no theory at the momen. With empty IP and Port, which

Yes we have the same problem even though no exceptions are raised. This
occurs with high traffic--especially sockets disconnecting with
errors/abort.

Thank you for the answer Wilfried
Im following your suggestios and I will test the Wsockets events today with

Ok. I see the point now.

Hello Miguel,
BGException is background exception. It comes from the message pump.
This means it can come also from your code in one of the TWSocket
events. To test put them all in a exception block until you found the
error (if it is over there of course).
Socket operation on a non socket means
