How to check what processes are using your swap
Here is a little script that will show you what processes are using your swap
http://www.nicktailor.com/files/swapusage
vi swapusage && chmod +x swapusage
copy paste below & save
./swapusage (to run)
#!/bin/bash
# find-out-what-is-using-your-swap.sh
# — Get current swap usage for all running processes output
# — rev.0.1, 2011-05-27, Erik Ljungstrom – initial version
