Hi Team,
We are using aspose slides (aspose-slides 18.6) with spring MVC for creating .pptx files which mainly contains, graphs, charts and images.Each generated pptx file will have around 200 slides.
this works fine for one user. But, when multiple requests comes in, out 5 only 2 will get pptx file generated, others will fail with java.lang.outofmemoryerror gc overhead limit exceeded. . Please help us with the exception and work around to work with concurrent user able to generate pptx files.
ByteArrayOutputStream bos = new ByteArrayOutputStream();
Presentation ppt = null;
Presentation pptUpdated = null;
try{
AsposeLicense.initiateLicenseForPpt(filePath.toString());
LoadOptions loadOptions = new LoadOptions();
loadOptions.getBlobManagementOptions().setPresentationLockingBehavior(PresentationLockingBehavior.KeepLocked);
ppt = new Presentation(path,loadOptions);
pptUpdated=updatePPTWithData(ppt, reportVO, actualSelObj, criteria); // code to populated data in ppt
pptUpdated.save(bos, SaveFormat.Pptx);
out = response.getOutputStream();
out.write(bos.toByteArray());
}catch(Exception e){
LOGGER.log(Level.ERROR, "Report generation failed : " + e);
e.printStackTrace();
}finally{
try{
ppt.dispose();
pptUpdated.dispose();
out.flush();
out.close();
bos.close();
}catch(Exception exeption){
LOGGER.log(Level.ERROR, exeption);
}
}
@natarajnb,
Can you please share source file so that we may further investigate to help you out. Before sharing requested information can you please try to use latest version of Aspose.Slides.

@natarajnb,
I think you are using standard values of jdk. Can you please increase heap memory. This will resolve your issue. If there is still an issue than please share complete environment details source file and complete sample code so that we may further investigate to help you out.
Thanks for your response, can you please suggest the approximate required heap memory for 10 concurrent user with each user generating a pptx of around 200 slides containings graphs,charts and images
@natarajnb,
I have observed your comments. You need atleast 3 GB heap memory to complete the process.
Hi Adnan,
Thanks for your response, we are using tomcat 8.5 with 4GB heap memory , But still we are facing out of memory exception :

Please help us on this issue.
@natarajnb,
Can you please provide JAVA_OPTS of Tomcat server that you used on your end.
Hi Adnan,
we have setenv.bat under tomcatinstallation/bin/setenv.bat, below is the configuration we are using.
set JAVA_OPTS=-server -Xmx8096m
@natarajnb,
Can you please share source presentation so that we may investigate further to help you out.
Hi Adnan,
As soon as LoadOptions() start executing we see the spike in the CPU utilization and reaches 100%CPU_Spike_Issue.JPG (86.7 KB)
LoadOptions loadOptions = new LoadOptions();
loadOptions.getBlobManagementOptions()
.setPresentationLockingBehavior(PresentationLockingBehavior.LoadAndRelease);
LOGGER.info(" presentation with load options ");
ppt = new Presentation(path, loadOptions);
LOGGER.info(" presentation with load END ");
Please compare the logger in the above code with the screen shot attached which shows the spike in the Java VisualVM tool.
@natarajnb,
I have observed the issue shared by you and also the details of usage of Aspose.Slides in your very first post. You are using big presentations (with multimedia, chart and tables contents) and having simultaneous requests too. Generally, the OutofMemory exception is thrown in cases where API is not getting required memory. In your case, I suggest you to please try increasing the Java heap size on your end. As far as CPU consumption is concerned, it is dependent on amount of load you put using parallel Spring MVC threads to serve the requests.
If you still feel that we need to investigate this on our end, please provide the working sample project, Operating System/Java and machine details on your end along with source presentation. We will try to replicate the situation on our end on provision of requested information to help you further.
