PDFXchange viewer hangs upon reading this PDF

[Rakushun]

Dear Sir or Madam,

in the attachment of this post, I send you a PDF file which was created using pdfTeX-1.40.10 some time ago. If I open this document with PDFXChange viewer 2.5.205, everything seems to work fine at first. But if I go to page 59, the viewer suddenly hangs and does not show the page even after a minute waiting or so. I have to kill it. Can you check this? It is strange, the Acrobat reader has no problems at all with that page.

Regards,

Michael


P.S.: The original file had about 6.5 MB, so I had to remove some pages to get it below 5MB. However, the application hangs with both, the old and the modified file, both at page 59.

Hi Michael,

Thank you for your post.

I did not have any issues when opening this document with the latest version of PDF-XChange Viewer 2.5.205.0.
Please make sure you have the latest version, you can find the installer for it here:
https://www.pdf-xchange.com/PDFXVwer.zip

Also can you test this with no other applications running? It may be that you have run out of system resources and we would like to eliminate that as a possible cause.

Thanks

Nicolas

Dear support team,

the ZIP file you sent me was exactly the one I installed preciously to testing and writing you this problem. I definitely have this version installed (see also pic0.jpg).

I did some more tests. I installed this software to some VMWare virtual machines with WinXP installed. On these virtual machines, the effect was that page 59 was drawn extremely slowly (took about 5 seconds to draw the page) and was not drawn completely. I opened the document several times, and every time, the amount of information drawn of this page was different (pic1XXX.jpg till pic3XXX.jpg).

On my main machine (Win7, 64 Bit, 4 GM main memory, dual core), entering page 59, the application hangs as described (pic4XXX.jpg). The Adobe reader 9.4 works well and fast in contrast (pic5XXX.jpg).

I also checked the available resources, there was enough available. As you suggested, I closed most of the applications, but there was enough available anyway (pic6XXX.jpg to pic8XXX.jpg). The pdfXChange viewer completely blocks one of my CPU cores, so I have 100% CPU on one core, 50% CPU on both cores in total.

I also tried to get some information about the point where pdfXchange stalls, using sysinternals' ProcessExplorer software (pic9XXX.jpg and pic10XXX.jpg). Probably that helps you.

Regards,

Michael

Hi Michael,

I managed to reproduce this - initially I had no ptoblems Viewing the file, but then when I tried to zoom in/out - the 59th page became completely blank and I had to kill the pdf viewer process from the task manager.

I've created a bug report ticket in our internal system:
#1635: PDFXchange viewer hangs upon reading this PDF
But the same behaviour is not present in the beta version of v3 of our Viewer - so I do not know if/when this will be fixed in v2.5.

Best,
Stefan

Hello Rakushun,

I just got a notification that ticket #1635 is now resolved. The fix will be available in the next build of our Viewer.

Best,
Stefan
