Now i am using NFS swap. Will let u know if still there is a problem. But the system seems to be working fine now. its better now.
But a small question. Is it recommended to use NFS swap for all the systems ? Because i haven't had this problem on other systems which have 32 mb ram. I am using gdm, gnome, mozilla, evolution, openoffice all these are very heavy. what are the advantages/disadvantages of using nfs swap. And what should be the general size of nfs swap ? Double the Ram ?
