OutOfMemory while working on Linux environment

Aspose.PDF Product Family
1

Hello.
We are experiencing the OOM issue while working with following code under RedHat Linux.
We don’t have it on Windows environments.

public async Task<(string bigImageName, string thumbnailName)> GenerateImagesFromFirstPdfPage(byte[] fileBytes)
{
await using var ms = new MemoryStream(fileBytes)
{
Position = 0
};

        using var pdfDocument = new Document(ms);
        using (var imageStream = new MemoryStream())
        {

            var resolution = new Resolution(300);
            var jpegDevice = new JpegDevice(resolution, 100);

/* IS FAILING HERE — > */ jpegDevice.Process(pdfDocument.Pages[1], imageStream);

Steps we tried to fix the issue:

  1. Update Aspose to 21.9.0.
  2. Set the application to x64 architecture platform.
  3. Update libgdiplus package on RedHat Linux.
  4. Set folder with msttcorefonts.

I also have a problem on ECS where I am getting an OutOfMemory issue when downloading a large PDF or multiple PDF’s. The box is also Linux based with 1 CPU and 4GB ram.

Like @DSDeveloper mentioned above we also have a memory issue where the machine stops unexpectedly. The issue does not happen on Windows.

We also have had to install the libs as @DSDeveloper mentioned.

We are using a USING block in C# in Asposes generation part therefore it should technically handle garbage collection in memory properly.
