Assembler Service error

Hi,

I'm using AssemblerService in my proces, but sometimes the following is printed to the log file, anybody know what this means?

I have noticed the following llines in particular (taken from the log-entry below):

1. com.adobe.livecycle.assembler.client.ProcessingException: ALC-ASM-S00-002: Failed to execute the DDX - error messages provided.

2. com.adobe.internal.pdfm.assembly.AssemblyException: PDFM_S02013: The "appendDocument" operation failed on " 3".

3. com.adobe.internal.pdfm.DocumentException: ALC-ASM-S00-008: Invalid PDF source document for 3.

4. com.adobe.internal.pdftoolkit.core.exceptions.PDFCosParseException: could not find xref section

Complete log entry follows:
