Hi
I added that code after I encountered the problem thinking iTextSharp maybe
doing something that is resulting in the stream being not closed.
Since I suspect this memory leak has something to do with file handles or
something like that, I was trying to force everything to close to see if it
helps, but it did not.

Joseph,
A couple of questions for you.
1. Why are you closing the strm? It is inside a using block and that handles it
for you.
2. Why are you closing the strm before finishing the PDF?
You should consider the following,
Remove strm.close();
Regards,
Howard Shank

Subject: [iText-questions] out of Kernel memory
Hi
I am creating PDF documents on the fly using iTextSharp. I noticed that the
server where I am running this process runs out of Kernel memory (System memory)
After about 50,000 files. I commented out all the code to see what is causing
it, and it seems the mere fact of opening a PDF document and writing something
simple like “test” and then closing it, uses a bit of kernel memory each time
which is never released, so as thousands of files are created the kernel memory
usage keeps climbing until my server finally shuts down and reboots. Seems to
be done by the simple action of opening and closing a pdf document.
For (int I = 0; I < 100000; i++)
{
Document pdfDocument = new Document();
String outputPath = @”C:\”;
String reportName = “test” + i.ToString() + “.pdf”;
using (FileStream strm = new FileStream(Path.Combine(outputPath, reportName),
FileMode.Create))
{
PdfWriter writer = PdfWriter.GetInstance(pdfDocument, strm);
pdfDocument.Open();
pdfDocument.Add(new Paragraph("test"));
strm.Close();
writer.Close();
pdfDocument.Close();
}
}
