Hello all

I have seen on our Linux production servers the memory consumption at 90% and above which is very rare on our Solaris servers. I heard that in Linux the memory consumption could be at 100% (some times) and the memory is completely managed in a different way when compared to other *nix platforms.Also I heard that the Kenrel manages page in/out's as desired and the only concern should be the swap space it seems. If the swap space consumption is also high ( I am not sure about the range of consumption in terms of %) on top of the RAM's consumption then only one has to worry it seems.

In this regard I am searching for some good documents and links on the net to know more about the "Memory management in Linux" and I appreciate your help.

Thanks

To briefly answer your question, Linux is a virtual-memory operating system like pretty-much any other these days. And all such systems want to use 100% of available RAM if they can... it's there, after all, and meant to be used. It's entirely normal, and good, to see near-100% physical RAM utilization at all times when there's anything useful going on.
