On the debian alpha and intel machines I have, renice seems to ignore my requests to renice a process to 20. According to the renice man page, a nice level of 20 should restrict the process to running only when no other processes are running. However, on the debian systems, a command like
renice 20 [jobno] doesn't seem to do it. When I look at the processes using top, the given job is listed as nice 19 and is using about 10% of the CPU. This does not appear to be the case on the RedHat alpha machine I have, where top reports 0% CPU usage and nice 20 when other user jobs are running. Is this a bug, or is top just wrong? I know top has problems reporting memory usage, so does it have problems with nice levels, too? Though, if I look at the reniced process (in this case setiathome) output, I can see it is still running even if there are other user jobs. Thanks.
