Memory Leak Problem at Adobe LiveCycle Server 9.0

Question

Hi All,
We want to upgrade our system to 9.0. During the performance test we have found memory Leak problem at ALS 9.0. I explain the detailed problematic issue below. Is there any body who has any suggest?
We have Adobe Livecycle ES2 9.0 SP2 installed on WAS 6.1. But also WAS on Windows Server 2008 R2. We call java web services from .Net Web service for generating PDFs.
On Java side “com/adobe/internal/pdftoolkit/services/javascript/GibsonMemoryTracking” class is causing Memory Leak problem at server.
Our .Net Codes. I copied below. First we generate PDF then we convert this pdf to static pdf.
First We call the GeneratePDF function.
public static bool GeneratePdf(Document document, byte[] pdfTemplate)
        try
            //Create a FormDataIntegrationService object and set authentication values
            FormDataIntegrationService formDataIntegrationClient = new FormDataIntegrationService();
            formDataIntegrationClient.Credentials = new System.Net.NetworkCredential(Settings.ALCUserName, Settings.ALCPassword);
            //Import XDP XML data into an XFA PDF document
            ALCFormDataIntegrationService.BLOB inXMLData = new ALCFormDataIntegrationService.BLOB();
            //Populate the BLOB object
            inXMLData.binaryData = System.Text.Encoding.UTF8.GetBytes(document.XmlData);
            //Create a BLOB that represents the input PDF form
            ALCFormDataIntegrationService.BLOB inPDFForm = new ALCFormDataIntegrationService.BLOB();
            inPDFForm.binaryData = pdfTemplate;
            //Import data into the PDF form
            ALCFormDataIntegrationService.BLOB results = formDataIntegrationClient.importData(inPDFForm, inXMLData);
            document.PdfData = results.binaryData;
            Utility.Log("GeneratePdf", "Pdf generated successfully.", LogLevel.Info);
            return true;
        catch (Exception ex)
            document.ReturnCode = "22";
            document.ReturnMsg = "Exception on generating the pdf";
            Utility.Log("GeneratePdf", "Exception: " + ex.Message, LogLevel.Error);
            return false;
Then We call the ConvertPDF function.
public static bool ConvertPdf(Document document)
        try
            //Create a OutputServiceService object
            OutputServiceService outputClient = new OutputServiceService();
            outputClient.Credentials = new System.Net.NetworkCredential(Settings.ALCUserName, Settings.ALCPassword);
            //Create a BLOB object
            ALCOutputService.BLOB inData = new ALCOutputService.BLOB();
            //Populate the BLOB object
            inData.binaryData = document.PdfData;
            //Set rendering run-time options
            RenderOptionsSpec renderOptions = new RenderOptionsSpec();
            renderOptions.cacheEnabled = true;
            //Create a non-interactive PDF document
            ALCOutputService.BLOB results = outputClient.transformPDF(inData, TransformationFormat.PDF, PDFARevisionNumber.Revision_1, false, null, PDFAConformance.B, false);
            document.PdfData = results.binaryData;         
            Utility.Log("ConvertPdf", "Pdf converted successfully.", LogLevel.Info);
            return true;
        catch (Exception ex)
            document.ReturnCode = "22";
            document.ReturnMsg = "Exception on converting dynamic pdf to static pdf";
            Utility.Log("ConvertPdf", "Exception: " + ex.Message, LogLevel.Error);
            return false;
Our System Configuration:
Expiry date: Never Version: 9.0.0.0,
GM Patch Version: SP2
Service Pack Version: unknown
ADOBE® LIVECYCLE® PDF Generator ES2
9.0.0.0
SP2
ADOBE® LIVECYCLE® Reader Extensions ES2
9.0.0.0
SP2
ADOBE® LIVECYCLE® Output ES2
9.0.0.0
SP2
We changed some configuration which is suggested by Adobe. But this change does not solve our problem.
Changed Configurations via ADMINUI

Hi Mahir,
Can you attach the results of this performance test where we can see how GibsonMemoryTracking class is causing the memory leak issue.
Also do you see any stackTrace in the LiveCycle server logs related to memory / heap when you run this performance test ?
Thanks,
Simer
