I'm just making guesses here, but:

 - It looks like the white pixels are only occuring between the "tiles". Do
they ever occur in other areas of the image, like in the middle of a tile?
 - If not, are the tiles individual objects? Are they completely flat? Is it
possible that rays are slipping through the cracks and travelling infinite
distances?
 - Where's the media that's *supposed* to be there? Do the white pixels only
appear where rays are passing through the media container?

Sorry for the delay in reply,
I had placed a panel behind the tiles to block the veiw.
The edia fills the whole room. But it didnt show all the time in the same
places as its very thin.
The problem was two things.
one was the media settings, The density map used filter in the color code.
and the reflection and phong was too high on the surfaces.
thanks for your time slime.
hmm that ryhmes......sprocket.
