New Post: out of memory exception thrown

Hi,

Im trying to run magick image in a multiple worker threads but it is occasionally throwing a out of memory exception despite there should be plenty of memory available.

I am using q16 any cpu version 7.0.3.501 and I am trying to do the following on 4096 x 4096 images

        MemoryStream outputStream = new MemoryStream();
        try
        {
            using (ImageMagick.MagickImage img = new ImageMagick.MagickImage(input))
            {
                img.ColorAlpha(backgroundColor);
                img.Format = ImageMagick.MagickFormat.Pjpeg;
                img.Quality = quality;
                img.Strip();
                img.Write(outputStream);
            }
        }

I know the images are big and that they take up around 128 mb in raw format.
I run 4 thread concurently and the used application memory goes between 700mb and 1200mb according to the task manager.

I am setting the ImageMagick.ResourceLimits.Memory = 16009916416 so that should not be the issue (while it is running I have around 7gb of free and available memory according to the task manager).

I also noticed that it saved a lot of image magick files to the temp directory which I was hoping to avoid as 128 mb of diskspace per image is rather much.

Any advice is appriciated
