My office running Ubuntu 12.04 Server version for nfs setting. Its works well for the past 6 months. Until i did the update last week, then my swap no longer working.
I am running intel i7 processor and 12G of RAM and 5G of swap memory. Previously this spec works well to support my office 20 PC. but after the swap memory not working, my network file sharing become very very slow.
Any idea how to solve and why is it happen?
