top

I used top command to print this on Linux box:

[root@localhost ~]# top
top - 23:38:38 up 361 days, 12:16,  2 users,  load average: 0.09, 0.06, 0.01
Tasks: 129 total,   2 running, 126 sleeping,   1 stopped,   0 zombie
Cpu(s):  0.0% us,  0.2% sy,  0.0% ni, 96.5% id,  3.4% wa,  0.0% hi,  0.0% si
Mem:   2074712k total,  1996948k used,    77764k free,    16632k buffers
Swap:  1052248k total,  1052248k used, 0k free,   331540k cached

I am not sure what Swap:0k free means in the last line. Is this normal behavior for a linux box to have value of 0

Thanks

On my new 32 GB system that has changed: It blocks when it starts swapping. Sometimes… >>> More
