| Hi Steven,
| The size of the document is very small, I doubt in this case its related
to
| that as sometimes the exact same document stayts around (in all cases Im
| seeing success and failure with the same info in the cache). It's a class
| that serializes to probably under 1k.
| Seems an exception occuring can possibly clear the cache, its being
| investigated now at:
