Hi everyone,
I was tasked with a very simple job of creating a web service that returns an attachment over MTOM.
Fair enough, I knocked up a flow with a SoapInput, Compute Node to set file properties, File Read node, another compute node to convert the fileBuffer from a BLOB to Base64 and a SoapReply node.

Works a treat with the exception of large file sizes. Seems to clunk out after about 15 Mb with OutOfMemory exceptions.

As this is not a mission critical piece of code (It is part of a test suite for another application) nobody except for me seems to care so much about the file limit restriction.

I know that loading large files into memory is a general no no with WMB but for curiousities sake I was wandering how else I could have gone about this while still using MTOM for message transmission.

Under the assumption that I can not parse the incoming message in segments, so it will always be a BLOB, is there anyway to overcome the file size limitation (beyond increasing memory available).

Using WMB 8 Fix Pack 1 running on Windows 64 bit.
