In the immortal words of Tzu-Hua Wang on 05/17/07 20:27: > Hi, > I added 2G RAM to my server. Is it necessary for me to alter the size of > SWAP? > My SWAP is 4G originally. Does this mean you now have 2G or you have 2G more ram? Typically, the rule of thumb is you need at least 1Mb more swap than you have actual ram. Something to do with system core-dumps, or some such. I forget exactly what the the reason was, but it's still a good idea to have more swap than physical memory, even if it's only a slightly larger. Maybe it was hibernation or something like that. Must go back and read up on it again Cheers Tim -- Tim Aslat <tim@spyderweb.com.au> Spyderweb Consulting http://www.spyderweb.com.au Mobile: +61 0401088479
