Application Hang on PDF/a export

Post by AnMuWK » Mon Apr 27, 2020 1:52 pm


within our application we are using the SDK to ensure to save a dedicated PDF file into a PDF/a file. At some customers we are seeing an application hang and do not have any more ideas to solve this issues. I attached a sample csproj file which show how we are trying to export the file.
The sample works perfectly on several different systems. But the customers where it does not work are using Terminal Server 2016.

I made the sample as a console application and added a progress interface. I also added the document which I tried, but it also happens with several other documents.

We are using version 8.0.337. It seems that with version 8.0.336 it worked. If we are changing back to the older version the customers seem not to have any issues.

At one customer the last entries in console are:

Pos: 2,37732426303855
Pos: 2,37913832199546
Pos: 2,38095238095238

So it looks like conversion is starting but hanging up at some time.

We are at a german system so UI culture is "de-DE". Also we are using "side by side", we are not registering the COM-classes.

is the file we open and try to export as pdf/a.

is the sample solution.

Hello Andreas,

Can you recreate this in the End-User Editor?
