Its a bug in the xupdate code that xindice uses. What happens is when append tries to find a node but can't it throws a execption and doesn't clean up after its self. I wrote a patch that you can apply to the source code that you can get from here: http://sourceforge.net/projects/xmldb-org/.
I would also be careful with having multiple update statements on a collection. Xindice has a bug that will start executing each statement multiple times. See bug 25892. I wrote a patch: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=30878, that fixes the multiple insert problem when working with xupdates across a collection. Use the second patch in that bug first one had formating issues.
