I took 30sec for on pic. but I found 30 dead pixcels...
It is general happening or problem?

You're going to have to provide a bit more info than that. How are you distinguishing hot pixels from noise, which is inevitable to some degree in a long exposure?

Can you post the photo, and some EXIF data from it?

I assume this is on the K-5 that you have posted about before? If so, the K-5 can map out dead pixels by itself. Run "Pixel Mapping" in the menu. It will find and mask bad pixels.
