[Boost-users] Known issues loading lots of objects with xml_iarchive?

I am serializing a LOT of objects, one per file. I can create XML for many thousands of objects with no issue. However, when trying to load a few hundred objects (using a separate program, btw) I am hitting a boost::archive::archive_exception with a stream error while loading around the 161st file, which I believe based on stack traces is coming from within boost::archive::basic_xml_grammar<char>::parse_end_tag (). The approach I'm taking is fairly textbook, so I'm curious if there are known issues with loading a lot of files, etc. Any advice appreciate. Thanks, Chris Gillett
