My question is about swap-space: Traditional knowledge recommends swap = 2*RAM. This would mean 32GB swap (!). Should I really go for 32GB swap space? Or will e.g. 16GB (= RAM-size) be enough? Please note, that I don't do kernel debugging etc. on this machine - just a production machine used for network monitoring (Mrtg, nfsen, cacti) TIA for any clue, -ewald
