For the size of the DNGs, have you tried running them in the DNG converter with (lossless) compression on?
Please post a link to a sample raw file with this problem.

Let me know once you have downloaded so I can remove it
or need more examples or want to talk over the phone.
the lines are in the same place for all files.
they are more visible on the sides, horizontal, just above the grass and also in the skies.
I have also opened a support case #0180497750
Thanks for the quick response!
Initial guess as the extreme over-sharpening applied is showing some low level sensor defects. Capture One may be better at patching these defects.
1. the lines doesn't show at all on Capture One software even with full sharpening.
2. even without sharpening you can still notice the lines.
are you going to try and improve the way you process the Phase one raw files or from your point of view its not adobe issue and I should use Capture one for processing my raw file?
I'll try, but I cannot make any promises at this point since I will probably need some information from Phase One to fix this.
Following does not alleviate the problem, but it may shed some light on the underlying reason.
Phase One are fooling their customers with the promise of 16bit depth. However, in fact that is only 14 useful bits; the two low order bits *must not* be used, for they represent mainly the pecularities of the hardware.
The following capture is from a P25+ raw image (converted in DNG by the Adobe DNG converter), but only the two low order bits are processed. These should be random on their own, as theoretically they would represent the finest transitions. The two thin vertical lines show the seams between the chips; their location depends on the particular camera copy (I have seen one or two seams, i.e. the sensor is made out of two or three chips, but perhaps there can be more).
The horizontal stripes cause posterization if an extremely underexposed image's brightness gets adjusted; the seams can become visible as thin lines.
The image is in the "native" (landscape) orientation. The orangy rectangle is not part of the image.
