We are running System 11.0.3 on NT4.0 SP3 and are beta testing a PowerBuilder
application with users at a remote site which is connecting to the Sybase server
using IP routers. A couple of times over the last week and a half we have had the
following error on the client workstation:

DataWindow DB Error: Select error: ct_cancel(): network packet layer:
internal net library error: Net-Library operation terminated due to
disconnect

Does anyone know what this message 'really' means in Sybase terms. Does it
actually indicate a problem with the Sybase client or server software or can other
layers in the connection (eg NT server IP protocol) cause this error to be reported
anyway. I'd really appreciate any clues.
