| Just done a quick search of the forum and found this; http://www.webhostingtalk.com/showthread.php?t=1146872. Have you tried restarting your server to see if it drops? Have a look at that thread.

| Just a wild guess, is there a cron job running when you noticed it?
Also Linux does have the tendency to use Swap for processes that are not frequently requested, leaving the RAM freed up.

| Hello,
You can simply use swapoff -a and swapon -a commands in order free up swap memory.
Its quite hard to get reliable information about which process is using swap memory. But give a try for following bash series (commands) in order to find and those processes.
#=========================================
#!/bin/bash
SUM=0
OVERALL=0
for DIR in `find /proc/ -maxdepth 1 -type d | egrep "^/proc/[0-9]"` ; do
PID=`echo $DIR | cut -d / -f 3`
PROGNAME=`ps -p $PID -o comm --no-headers`
for SWAP in `grep Swap $DIR/smaps 2>/dev/null| awk '{ print $2 }'`
do
let SUM=$SUM+$SWAP
done
echo "PID=$PID - Swap used: $SUM - ($PROGNAME )"
let OVERALL=$OVERALL+$SUM
SUM=0
done
echo "Overall swap used: $OVERALL"
#===========================
Save this code in file called 'getswap.sh' then chmod 755 getswap.sh finally ./getswap.sh

| Hi,
What is the swappiness parameter set in the sysctl.conf file or in /proc/sys/vm/swappiness ?

| What operating system are you using?
It does indeed and absolutely nothing to worry about. Unfortunately cPanel for example still considers this bad and leaves a big red exclamation point scaring users.
