I think, by such a high value for HZ, you are not allowing the system to do anything usefull except handling timer interrupts. At this freq, kernel will only keep on handling the timer interrupts and will not be able to give attention to user processes, i mean non-interrupt conext code, hence it gives a feeling that sytem is hung, where as system is busy in handling only and only timer interrupts. regards, Gaurav
