Viewer on Windows leaking native memory


#1

When rendering html views of documents it continuously leaking native memory.
Heap is ok, metaspace is ok. Only applies when rendering, i.e. not when documents already rendered and reading from cache.

Windows server 2012 r2, also confirmed on Windows 2016
JRE 1.8.0_152

Reproduced by the attached code.

doc-renderer-debug.zip (7.5 KB)

Run configuration
-Xmx512m -Xms512m -XX:MaxMetaspaceSize=512m

Resulted in:
memory-leak.jpg (16.1 KB)

Ended up around 2gb before exited.

This is a consistent behavior for any of the documents we been rendering (html).
Here is a document set that you can use and try to reproduce the issue.

@dalbrekt,

Thanks for your patience. We have investigated your reported issue in your mentioned environment but unable to reproduce it for the random documents. Please watch here the memory consumption during the rendering of Cisco State Cooperative Contract.pdf document. You can download the sample application that we used to render the documents from here. You can test the provided sample application in your environment to check the results. Following are the visual representation of the heap and metaspace used for the rendering of some random documents that you provided us in the previous post.

Tested but it’s hard to tell by just running one document and where the content is of images only.

I made some modifications to be able to render all documents in a folder. Ran the test with the whole document set I provided from the command line (Xmx512m) and ended up with 1.5gb memory foot print just before completion.

Please run this test and let me know the outcome.

Hi.
Now it’s been over a week since last contact and still no progress report.
It’s worrying us that you don’t give this more attention considering it is core functionality and the component is more or less useless if this is not fixed.

Can you please give us an estimate of when this will be fixed.

Regards, Tony
