top doesn't show any Process in idle-Mode

[Michael Schuh]

Hello,

sorry for the time ago, i haven't an FreeBSD-Box on my Work.

The CLI-Optin -S doesn't really help me.

I will test the patch from Stefan Esser, but i think
my Problem are not alone SRUN-Proc's.

if i run TOP with the CLI-Options -I -S so i should see
Processes with status RUN and SRUN, if i was right.

I have also running top described as above, and now i do a
make -j 16 cleen cleandir cleandepend under /usr/src, so
i unterstand things right i shoud see minimum 3 or more
Processes with status RUN ( System was Sempron 2400 @1800MHz).
But i shows only one and this very short, but if the system runs i could see
an process named pagexxxxx, and if the system was idle i can see an
process with status SRUN called idle....

So i get the time i will test the Patch from Stefan.
If  i getting new values and experiences i come back again.

Tahnks to all and

best regards

michael
