Well, actually I was trying to add a ton of dcm files packed in the large (around 20 GB each) archives on my server. After copying them as-is in the 'incomng' folder, most of them didn't make it to the server and stayed there after a long time (days). I unzipped the archives and added them on the server by small portions, and everything seems to be OK, i got nothing new in DicomTrouble.log besides this

and the same kind of errors I mentioned above. Maybe the files just stayed in the queue for too long. Sorry for bothering you.
