If i do understand you correctly this is a misconception: If a process is used very rarely (like, say, once a day) and otherwise is idling it will get swapped out. This would add to the usage numbers of the swap space but would pose no problem to the machine at all. The swapping in would take some time, true, but only once a day. After that the process would get swapped out again, until it "rests" in the swap.

Obviously this is not the case here, so my point is not connected to the problem the OP raised and of merély theoretical interest. I just had a case where a customers sysdmin pointed to the output of "lsps -a" and demanded more memory whereas the machine was already having enough memory at all. This was easily shown by analysing the vmstat-output.

gnome-disks

GNOME-DISKS(1)							gnome-disk-utility						    GNOME-DISKS(1)

NAME

       gnome-disks - the GNOME Disks application

SYNOPSIS

       gnome-disks [OPTIONS]

DESCRIPTION

       gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks
       and block devices.

       The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is
       invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application
       instance will be used and the gnome-disks command will exit immediately.

OPTIONS

       The following options are understood:

       --block-device DEVICE
	   Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda).

       --block-device DEVICE --format-device [--xid WINDOW-ID]
	   Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog
	   transient to the given XID.

       --help
	   Prints a short help text and exits.
