Hi Peter,

There is not enough information in the message. If you can provide monitor
reports that last a minute or so (several reports from each computers), then
that may provide the necessary information.

Also, it will help to know what changes you made to Spread. From the reports
I see you made at least some changes to flow control, which basically reduced
the effectiveness of Spread's flow control.

Cheers,

	:) Yair.
