SWAP - how to enlarge. Recommended size

[Wingman]

In me Plesk server I got a 250 drive with 4 Gb swap. In Plesk CP -> statistics in show a red 100% bar on swap. I really didnt think of this when I installed FC5.

So how can I change/enlarge swap without reinstall the server?

Recommended size of swap? is there a % or size in Mb that is recuired??

see `man mkswap` and `man swapon` to know how to create an additional swap file, but I do not think that one more swap is what you really need. If your existing 4gb swap is filled, it is definitely not normal, the most probably there's incorrect report in Plesk.. try to run `top` or check /proc/meminfo to see the actual swap usage.

swap size is usually made as RAM x 2, but it is done for hypothetic peak loads only. Most of systems almost never use even a quarter of allowed swap size in their lives. If your system starts using swap, it is must better to increase RAM.
