Hi Brian, The CappedInputStream doesn't count the content of the <cmisra:base64> tag. If you remove that, is the XML small? Which XML parser do you use on the server? OpenCMIS is tested with Woodstox and can handle very, very large content streams with this parser. Other parsers might work differently.
