How do I find out who uses swap?

[Maciej Soltysiak]

Hi,

I have a problem for some time with that the amount of swap
being used constantly increases up to the moment where
the swap is used in 100% and the machine deadlocks.

How do I find out which proceses use swap and in what amount?

I tried using top and sorting by SWAP, it shows this:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  SWAP COMMAND

Or should I look at VIRT or MEM ?
I am confused.

Maciej
