Exception sending DIMSE: OutOfMemoryException

[Toshko Andreev]

Greetings I am getting the following exception when trying to send a JPEG Baseline encoded file (it is very large)

[Error] Exception sending DIMSE: OutOfMemoryException { Message: "Exception of type 'System.OutOfMemoryException' was thrown.", Data: [], InnerException: null, TargetSite: Void DoWalk(Dicom.IDicomDatasetWalker, System.Collections.Generic.Queue`1[Dicom.DicomItem]), StackTrace: "   at Dicom.DicomDatasetWalker.DoWalk(IDicomDatasetWalker walker, Queue`1 items)

   at Dicom.Network.DicomService.SendNextMessage()", HelpLink: null, Source: "Dicom.Core", HResult: -2147024882 }

And then after that:

Thanks for reporting, Toshko!

In the upcoming 3.0.2 release, we have made some enhancements regarding networking memory efficiency. In the best of worlds, those improvements will help you work around this problem. Don't hesitate to download and build the source already today to test whether it works or not.

Otherwise, if you believe this is something we need to fix, e.g. with improved error handling or reporting, please post an issue in the Github repository.

Best regards,

Anders @ Cureos
