AW: Is there anybody out there?
Hi! we had he the same problem. In fact, it was the ImageCache that was not released and made the jvm crash. Try to release the cache by your program or try the patch I've posted for fop 0.20.5 ( Bugzilla Bug - ID 20407). Hope this helps. Cheers Mirko -Ursprungliche Nachricht- Von: Nandina Srinivas [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 17. Juli 2003 07:44 An: [EMAIL PROTECTED] Betreff: RE: Is there anybody out there? Dear Ali, I know fop is very memory intensive but what you are saying is a memory leak. We also use fop to generate PDF reports using servlets inside tomcat. It is generating reports of size 20 pages with ease on a 256mb RAM machine with -Xmx set to 128m. It takes upto 90mb for generating a pdf of 25 pages. But when I generate it again it is releasing memory. I doubt there is a leak in the driver code embedding FOP. Please check on it or if possible try to publish it. Somebody might help. Regards, Srinivas. --- ali farahani [EMAIL PROTECTED] wrote: Dear Thomas Here is what happens. I have closely watched the memory usage of FOP: I have a report with around 17 pages. One table with 12 columns. I use Velocity to put the data inside the FOP template. When it starts rendering the report (PDF or print preview) it consumes 50 MB. Second run another 50MB, third run another 50 MB , then with 256 MB RAM , when I go for forth run, CRASH BOOM BANG! Out of memeory exception. My users usually use the report during the day ( 7 hours) 10 to 20 times. So even 512 MB RAM workstations get out of memory easily. Running it under another JVM is a good idea but as you know it is not feasible from performance point of view. Ali -Original Message- From: Thomas Sporbeck [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 16, 2003 6:35 PM To: [EMAIL PROTECTED] Subject: AW: Is there anybody out there? Does this happen with the first report after starting the Java VM or later on (after some reports have rendered correctly)? Perhaps you may start FOP in a separate VM and exit it after the report has done, that's not ideal for performance but for stability.

Out of memeory exception. This sounds like a self-inflicted problem. FOP does not lock memory across rendering runs if you release the Driver and Renderer object, with the exception of the external graphics cache. The cache should not require additional memory for rendering the same document a second time, and locking 50MB would require quite a few hi-res images anyway. Therefore, check whether you release the Driver object you are creating, or at least call the reset() method after render() or run(), although the latter may still result in leaking memory. In addition you might try FOPImageFactory.resetCache() to clear the image cache. J.Pietschmann - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
