Here is a small utility I have used to check the amount of swap space on linux machines.
Generally you would like to have 1 to 1.5 times the amount of swap space as you have RAM.
On a linux machine you can check the swap values with the following command run from a command prompt.
swapon -s
Hope this helps.
