Chris,

Some thoughts/questions:

Are you getting any error messages in the job log related to the data
queue not being large enough for the data? Any error messages in
QSYSOPR? We've used the technique of overriding ICF files to data queues
without any problems in X.25 applications, so I would look for something
like this. Do you have a communications trace of the session? If so,
look to see what the AS/400 does when it receives the data. If it issues
an X.25 reset this would be an indication of configuration mismatch.

hth,
Patrick
