Resolution

a) Ensure listen port was set to no maximum size restriction set.

b) Ensure there were no references (audits including add audit messages to policy) that were referencing request or request.mainpart

c) Ensure streaming assertion did not have buffering just streaming.

d) Ensure no limit message size assertion exists.

e) ensure cluster wide properties io.xmlmaxpartbytes=0

f) ensure route was using default request.

Select target message should be default (request).
