Here is a handy script that will check all processes and report what is swapping
#!/bin/bash
for pid in `ps x|awk '{print $1}'`; do
result=`cat /proc/$pid/status|grep VmSwap|awk '{print $2}'|grep -v ^"0"`
if [ ! -z "$result" ]; then
programresult=`ps x|grep $pid|grep -v grep`
if [ $? == 0 ]; then
program=`echo $programresult|awk '{print $5}'|grep -v ^grep`........
