OutOfMemoryError posting large file

           Summary: OutOfMemoryError posting large file
           Product: Slide
           Version: 2.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: WebDAV Server
        AssignedTo: slide-dev@jakarta.apache.org
        ReportedBy: robert.leathley@ricardo.com


Trying to put a large file (133MB) in the store (TxFileStore) causes the JVM to
run out of memory.  Using java -Xmx500M fixes this problem, but the intention is
to transfer much larger files (>= 2GB).

This appears to be due to the server using XServletInputStream which caches the
entire file in memory to make the stream re-readable.

I may be able to spend some time creating a patch for this problem - do you have
an approach in mind for solving this?  In any case it would be good know if this
is likely to be fixed within the next month or two and if there are likely to be
other issues with files of this size.
