If so, that is a sender violation, which as explained in Paul's response may or may not be caught by the receiver. If Msg 1 is completed *before* Msg 2 is placed, Msg 2 will be rejected as having an invalid MSN (it would be taken as being 2**32-1 ahead of the current location). In either case a 200 byte receive will be reported to the ULP. The question is whether the Stream is almost immediately thereafter torn down. -- Caitlin Bestler - [email protected] - http://asomi.com/ http://asomi.com/CaitlinBestlerPublicPgpKey.html
