PDF in doc library causes memory leak ?

Sounds like a bug in the 3rd party library used by Alfresco to process PDFs (PDFBox, Tikka or OpenOffice etc.)

Thanks,

Kev

in the mean time can someone tell me how to disable pdf processing so that pdfs are treated like unknown file types ? Thanks
EDIT: I've commented out the PDF file type in mimetype-map.xml, and the application runs fine now.
