Weird glowing edges and dirty edges in interior scene

[rubensabou]

I'm making a interior scene with a single HDRI light and exterior portals (excluding glass object). I've got some weird glowing edges and some dirty edges. By the way checking Retrace in LC makes some of the glows disappear but all my image get dirtier and my render time increase like three times. Increasing LC subdivs and sample sizes, makes the glows disappear but my shadows get darker and the edges dirtier. My wall material is a simple white. I attached my V-Ray settings.

Try turning off "store direct light" in the light cache.

So I've found out the solution. The model was imported from Sketch Up so when i zoomed in, some of my walls didn't really intersect. I tweaked the geometry, by over-intersecting it. I've checked in IM the detail enhancement and maximized in LC subdivs to 2000 and sample size to 0.007. So now I have clean edges. This worked for me.
