javax.xml.stream.XMLStreamException while indexing

[Pieter Berkel <pi...@gmail.com>]

I've recently encountered a strange error while batch indexing around 500
average-sized documents:

HTTP Status 500 - null

Most other reports of this exception refer to an XML parse error on a
particular line / column, however this is not the case in this situation.
It doesn't seem to be a problem with the data either, since it fails on
different sets of documents on every occasion (i.e. I can't find specific
input data to reproduce this problem).  Increasing / decreasing the number
of documents still results in the same error.

The system I'm using consists of Solr 1.3 dev (compiled from SVN on
2008-07-21), Tomcat 5.5.23, and Sun Java SDK 1.5.0-11-1 running on Ubuntu
Server 7.10 with all current updates applied.  Has anybody else experienced
a similar problem to this? Would upgrading either Tomcat / Java help in this
instance?  Thanks in advance for any help.

regards,
Pieter
