Ghost Lights

In this comparison you can see the same photo, the first has an exposure of 2 sec, the second of 30 sec.
In the attachment there is a snapshot of exif data of both photos.
The strange is that in the 30s one there is a large amounts of "ghost lights".
Anyone knows if this is a known problem, a software bug or a malfunction of my K7 sensor?

They look like hot pixels to me; can happen in long exposure as the sensor warms up. Maybe try running pixel mapping? It's in (I think) the wrench section of the menu.
