Hi , PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 23921 kapil 25 0 811m 510m 6260 R 99.9 14.5 9:50.62 java Here , the process 23921 consumes all the cpu ( but in summary , cpu is shown idle , this is strange) Why does this process consume all the cpu? What does it do? Can you check: Strace -p 23291 ? What happens when you stop this ? Does the system work faster?
