I've developed a few rolls of TriX 400 on a Mamiya c330 pro, and the negatives have been fine aside from excessive linear silver density at the sides of most frames. These linear densities extend beyond the bounds of the frame. The negatives themselves are fine otherwise with no fogging or dents. The printed images are lighter on edges where these densities are. See attached images.

I'm developing in Rodinol 1:50 at 20degC for 9minutes with typical agitation for first 30s then 10s/minute thereafter. citric acid stop, ilford rapid fix. I'm using a Nikor stainless steel tank and reels with 15 oz (450mL) developer as per instructions. This leaves adequate headroom. I do not think these are edge effects, though I could be wrong. They almost look like light reflections from the silver-colored film guides inside the camera. Any ideas are much appreciated. Thanks!

Is this a new phenomenon from this combination of camera and processing equipment? Or have they been performing correctly in the past?

I have shot about five rolls through this camera, and they all had the same defect. I have no prior experience with MF film or cameras, so I have no prior comparison.
 
I would suspect some reflection or other source of light fogging in the camera.
How are the light seals, and is the back latching securely?
