Pdf creator crashes under high load

Hi, not sure if anyone can help or not.

We are using PDF creator to print a high number of documents over a period of time with 5 being sent to the queue every minute over a period of time. For the first couple of hundred it seems to work fine but between 200 and 400 we get two sorts of problem.

The first is that it starts producing PDF files that are just .PDF with no title, the second is that it just doesn’t print at all. If we re-start the PDF creator it carries on and works fine, but obviously this is a pain to do all the time.

We tried upgrading to version 1.6.0 but still had the same issues. Has anyone seen anything like this or does anyone know what could be causing it and how we could work around it.
