I'm sorry but I can't reproduce it. I checked the all the memory pools and
handles while it was running and the values were steady. There are no memory
leaks, file handle leaks or any other leaks that I could think of. If the
problem is in the remote server you may just write files to it without
iTextSharp to see if it's not a network problem or something else related to
your particular configuration.

Subject: Re: [iText-questions] out of Kernel memory
Change your test to the following and let it run for a few minutes and you
will see the kernel memory climb
It does not happen in your example because you are writing to the same file
name each time. Seems to be as the number of files generated increases, the
problem occurs.
Another interesting observation, The kernel memory increases out of control
on the server where the files are being written to, not on the server where
the application is running. This is what was throwing me off to think it is
related to IIS or console application. Try the test below and let it run for
a few minutes, eventually it will run out of kernel memory. The only
modification to you code is that I am generating a different file for each
loop iteration.
for (int i = 0; i < 1000000; i++)
{
Document pdfDocument = new Document();
String outputPath = @"c:\test";
String reportName = "test" + i.ToString() + ".pdf";
FileStream strm = new FileStream(Path.Combine(outputPath,
reportName), FileMode.Create);
PdfWriter writer = PdfWriter.GetInstance(pdfDocument, strm);
pdfDocument.Open();
pdfDocument.Add(new Paragraph("test"));
pdfDocument.Close();
}

I have this code running and all is ok.
for (int i = 0; i < 1000000; i++) {
Document pdfDocument = new Document();
FileStream strm = new FileStream("c:\\atp.pdf", FileMode.Create);
PdfWriter writer = PdfWriter.GetInstance(pdfDocument, strm);
pdfDocument.Open();
pdfDocument.Add(new Paragraph("test"));
pdfDocument.Close();

Yes I am using V4.1.6.
The .NET I have installed has version 2.0.50727.42
Which I believe has the latest service packs.

Are you using iTextSharp 4.1.6? If you are using .NET 2.0 without SP1 you
may have leaks due to leaks in the framework.

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();
}
}
