Swap partition always full
 
Hi people,

I administer a Debian server which reports swap always full. It's funny because free output doesn't seem show me that:

Code:
            total      used      free    shared    buffers    cached
Mem:          629        613        16          0        36        332
-/+ buffers/cache:        244        385
Swap:          337        337          0
Anyone can to give me a tip?


Thank you.

Upgrade the RAM to at least 1 GB. If it starts using swap, optimize the services and use sysctl to optimize vm of the kernel.

Thank you for answser. Currently it runs Postfix mail server, Apache web server and share Internet to around 100 computers. I am thinking of separating this server just for email, and keep other one for the web server and sharing using Debian 4 (today runs Debian 3, 2.4.26 kernel). The web server hangs while a big email account is accessed...

Despite what many say, the old rule of twice as much swap as ram is still a good idea. If you want speed, then adding more ram will help (if any swap is being used). Even after you add the extra ram I would up the swap too.
