view story

http://www.unix.com – Hi All, I have a RAM of around 11 gig and swap of around 18 G in my Linux Server. But at some times , I find that All the RAM and 5 gig of swap is used in server...and i also got some advice from our discussion forums to increase the RAM . But nowadays what happens is the all the RAM and all the swap are used and there are no free memory left in both ....so the system is performing very slow. Pl let me know any work around behind this.... (HowTos)
