I'm running Debian Lenny (x86_64) on a cloud VPS (Xen) and top command tells me there are 210 processes running and 209 are sleeping:
top - 14:49:29 up 15:18, 1 user, load average: 0.09, 0.11, 0.05
Tasks: 210 total, 1 running, 209 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 532288k total, 437316k used, 94972k free, 30584k buffers
Swap: 1048568k total, 408k used, 1048160k free, 219772k cached
And here is what ps aux command gives me:
