Will watch replies and post more when I know more. Kinda new at this.
Do you have the strace from the sending side?
Yes...I hope I'm not posting too much info but here goes. It's worth
mentioning that this data is never on the internet, only isolated lan or
loopback. We are using an older version of the GSOAP toolkit (a
sourceforge project) and are in the process of porting to their latest
version.
In addition to the straces below, I have ethereal screencaps in jpeg
format if anyone wants to see those...2 x ~400k. ea.
Thanks everyone for pondering this. I tried to get the socket setup and
several full transactions from each side of loopback.
