Mystery error in log

I’m using Orthanc as a DICOM router. I’ve got these lines appearing in the error log file. They seem to be appearing randomly, but mostly in groups of 3.

There are no images being sent at these times (i’m logging this separately, so am certain about this)

Can anyone tell me what this is all about?

Hello,

Please could you provide your full configuration files? What is the manufacturer and model of the modality that your Orthanc router is sending images to?

It looks like a problem in the receiving modality, presumably when the DICOM connection is closed by Orthanc after a timeout.

In your configuration file, you should try to set the “DicomAssociationCloseDelay” to “0” or to set the modality type to “StoreScp”.
