Swap usage by top and free command doesn't match

Its rather confusing, the output of top command is below:

Quote:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND
25303 mysql 15 0 2968m 708m 4948 S 38.2 9.0 225:26.20 2.2g mysqld

The "swap" field of top is described by the manpage as: "The swapped out portion of a task's total virtual memory image."

But the output of free command suggests something else and it does tally with the output of swapon command:

Quote:
[root@server ~]# free
total used free shared buffers cached
Mem: 8046000 7476800 569200 0 296012 5291468
-/+ buffers/cache: 1889320 6156680
Swap: 4192956 61320 4131636

[root@server ~]# swapon -s
Filename Type Size Used Priority
/dev/cciss/c0d0p2 partition 4192956 61320 -1


So why is this discrepancy? How would i determine which process is using how much swap?

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
