Transcode Exception when transferring between two Orthancs

I am seeing a transcoding error when transferring some studies between two Orthancs. The studies are large enough that I have not tracked the error down to a specific DICOM instance. I’m working on that.

The two orthancs are configured similarly when it comes to all the accepted Transfer syntaxes, unknown SOP classes, GDCM configuration… all the things I could think might affect this transcoding issue, though I clearly am missing something.

The fact that the file was accepted and stored by the first Orthanc and only seems to generate an error when transferring to its sibling has me baffled.

The number of instances appears consistent on the sending and receiving Orthancs. So I’m not sure if the particular instance transferred despite the exception or whether this is more a warning message than a problem.

If I can track down the message to a particular instance, I’ll repost here.

If anyone knows I can just ignore this message, let me know.

Thanks,
John.
