Working with some pptx files consumes huge amount of memory which could lead to OutOfMemory Exceptiion

Dear Aspose,


we have a problem with Aspose.Slides .NET library version 16.9.0.
If we tried simply to open attached presentation, it consumes about 400MB of memory. If we tried to save it as pdf, total memory consumption rises to 2GB.
The memory is never released so it causes resource exhaustion on the server.
It is enormous amount of memory and when we tried to work with this file multiple times (in sequence), the program causes OutOfMemoryException.

The code to replicate is simple:
using (var presentation = new Presentation(@“c:\Temp\badOne.pptx”)) {
presentation.Save(@“c:\Temp\badOne.pdf”, SaveFormat.Pdf);
}
Can you pls fix this problem. It seems that there is some kind of memory leak in the library.

Best regards,
Ondra

Hi Ondrej,


I have observed your comments and regret to share that at present the issue is still unresolved. Actually, the issue is blocked owing to missing implementation in another issue of Aspose.Slides for .NET. So, it is going to get resolved in that issue first and then in this issue. The issue involves complex implementation and I have also requested our product team to share further feedback regarding the issue. I request for your patience till the time further feedback is shared by our product team and issue gets resolved.

We are sorry for your inconvenience,

Hi Muhammad,

for now as the first step we need fix high memory consumption that is connected to this feature.

Is it possible to separate this “stability” fix from implementing whole functionality in Aspose.Slides?

Our goal is product stability. This kind of effort will be really huge help for us.

Thank you.

Petr

Hi Ondrej,


Can you please try to use the x64 based assembly of Aspose.Slides that provides additional memory space for program holding presentation. This way you would not be getting Out of Memory exceptions.

Hi Muhammad,


can you describe detailed steps how to do this please.

But I think that this will not help in any way … our problem is that customer tried to convert few similar files to this and it finally consumed all the memory on the server and crashed anyway. Meanwhile, other applications has also lack of the memory because of this problem.

High consumption is one problem, but even more important is that the memory is never released after file is converted.

Hi Ondrej,


Our product team is investigated issue on their end. I like to inform that Aspose.Slides product team double checked on latest version of Aspose.Slides handling your presentation and we confirm that there’s no memory leak on loading or saving. All created objects are collected by GC as soon as the presentation is out of scope.
At the moment we’re still working on the performance and memory consumption improvements for presentations with large amount of data. We’ll inform you when these improvements are officially released.
