Thanks, Glen and Steve
I fonund out that the threshold is set by ManagedMemoryDataSource constructor and
it is instantiated in AttachmentPart (line 420 in 1.1beta source).
The second prameter of that constructor "maxCached" which is hard-coded value 1024.
(ManagedMemoryDataSource.MAX_MEMORY_DISK_CACHED seems not to affect the threshold, I
think)
The easiest way seems to modify that hard coded value to another.
But it should be configurable by the property of MessageContext.
I would modify so if I could...
Thanks,

solution would be to allow the default to be set on a per-engine or per-service basis.
Please feel free to try this out
and submit a patch.
