> Affects Versions: 3.2.1

> I'm having a problem with data loss in service mix. My servicemix log files contain random exceptions coming from the saxon engine. The details and exceptions are outlined below.
> I have a service assembly as follows: JMS consumer -> XSLT ( XML 1 to XML 2) -> XSLT (XML 2 to SOAP) -> HTTP provider. In addition, each service unit above is linked togethor using an eip:pipeline.
> I have a JMS client that pushes a single XML message X number of times. I want to emphasize that I push the same XML message every time. Hence, the content never changes during experimentation. In addition, every time I enqueue that XML message X times, I start from a clean slate. Which means, I shutdown servicemix, clear the data directory, then restart servicemix. The XML message I push is roughly 500 bytes of data.
> Roughly 50% of the time enqueuing 100 messages, I will see 100 messages reach the HTTP Provider. The other 50% of the time enqueuing 100 messages, I will see one or more of the following exception in my servicemix log file.
