Well, gosh...runnable means runnable...able to be run. If a process is not runnable it must be waiting for something to occur, like a signal or an i/o operation.
Swapped means that the entire process is sitting on disk in the swap area. If it wasn't swapped, it would be in memory.
Having processes swapped out is not good, it means you really need more memory.
If you really get exactly 30 such processes each time that you shutdown your database, I would guess that they are database processes of some kind that were sleeping, then got swapped, and finally awoken by the shutdown process. But I don't have much to go on here and that is just a guess.
