The top command showed the following information:
Mem: 132110132k total, 10447536k used, 121662596k free, 76120k buffers Swap: 16777212k total, 18446744063504593392k used, 10221735436k free, 7056188k cached
I'm puzzled by the information. It seems the state of the server is not very healthy. But why the Swap Memory used is much higher than the total and there is a lot free Swap Memory?
