TOAD crashes when viewing BLOB

Toad for Oracle & DevOps Toolkit
1

Hi all,

the new TOAD 2025 R2 crashes with the following scenario:

  • Select a BLOB field from a table that contains e.g. a PDF (this is what you know ;-))
  • Double klick the BLOB to get into the BLOB editor
  • Klick on the PDF button - good night

The frozen BLOB editor window even covers the task manager, so that it might be difficult to kill the frozen TOAD.

Best regards from Germany,
-Rainer

Hi Rainer. I'm not seeing this. How big is this PDF file?

Hi Brad, I tried with two different PDF files, one was 90 kB and the other 100 kB, I think this "peanut size" :wink: should no be the cause of the problem. Meanwhile I could repeat the crash behaviour on two different machines. At the moment I klick on the PDF button, the BLOB editor window freezes...

Hi Rainer. Would you be able to upload the two PDF files that are causing the crash/freeze?

For me, uploading PDF files makes no sense, because the crash happens with any BLOB containing a PDF file. In TOAD 2025 R1 it does not crash with the same PDFs.

Got it. Please enable logging in Toad Options, recreate the crash/freeze, generate Support Bundle and upload it here. Also, are you seeing any related errors in Windows Event Logs under Application?

Hi Rainer,

The third party component that we use to display PDFs was updated between Toad 2025 R1 and 2025 R2. It's entirely possible that the new version has a problem with your PDFs that the old one did not.

Is there any way you can send us a sample PDF? I don't think it's size-related, but maybe there is something in the content that is crashing the new one.

Thanks

John

Here are my support bundle and the Windows event log entry reporting the TOAD crash. Hope this helps...
