Hi,
The logs look normal as far as I can see: the database is always updated to the newest items recieved. So for me this looks like a bit like a database corruption problem. Which database are you using? However, if you see items in the header corrupted this cannot be from the database. It is strange that only the patientID seems affected. The patient name is not processed different at all as all other DICOM tags. The processing is that DICOM tags are entered into the database but never the other way around.
