Ok, thanks, so there really should be no difference between a report where all the URLs resolve and a report where none of them resolve?

Unless you set that property to avoid it. File is opened to read to check file type and next stage is to read file, these 2 steps can be far apart so connection may need to redone. Thanks -----Original Message----- From: Carl Buxbaum [mailto:[email protected]] Sent: 07 January 2014 15:47 To: [email protected] Subject: running out of filehandles Hi all, this is directed toward the developers: We have a customer who recently encountered an issue when running a FOP 1.0 report in an environment where none of the images referenced in the report existed. All of the references were URLs to images served by our application through a servlet. Our servlet writes the image bytes to the ServletOutputStream. I verified that I close all resources in a finally block (I do not, of course, close the Output Stream). If the file does not exist, I return a 404 not found in the response. When the images do not exist on the server, the platform runs out of file handles. They get this error: java.net.SocketException: Too many open files After researching a workaround, I had the customer add this to their Java startup -Dorg.apache.xmlgraphics.image.loader.impl.AbstractImageSessionContext.no-so urce-reuse=true This fixed it, but we are unclear on why the customer would see a difference between a server where all the images are available, and where the images are not available. In their production environment they never had this problem. Is it possible that the URL resource (and/or the ServletOutputStream) is not being closed when the response is 404 not found?
