| |
Just installed RedHat 7.3 with kernel 2.4.18 and noticed that my network no longer functions when my CPU usage is at 100%. Looking at the priorities of the application that I was running showed a priority of 35 (thats what `nice ./test` produces). Then looking at the priorities of all the other processes shows a range from 15 to 35.
All the main kernel processes run at 15 except ksoftirqd_CPU0 and ksoftirqd_CPU1 which run at 35.
None of the documentation on my system (`man nice` etc...) mentions anything about priority levels between 15 and 35, they all say -20 to +20 (as it used to be).
So, why the change the priority levels? And why my test app (at any priority level) starves out my network?
I am running an SMP box.
Thanks.
