Hello list,

is anyone actually getting WCHAN information from either ps or top? To try it just use "ps opid,wchan,cmd". I only get dashes, any idea why?

man ps wchan WCHAN name of the kernel function in which the process is sleeping, a "-" if the process is running, or a "*" if the process is multi-threaded and ps is not displaying threads.

That said, I only get a dash for the ps itself, and sometimes also for the shell.

PID WCHAN CMD 4040 n_tty_ -zsh 4620 rt_sig zsh 4626 poll_s irssi 12880 pause screen -r 12942 rt_sig /bin/zsh 14936 rt_sig /bin/zsh 14939 poll_s cmus 23759 poll_s vim lib/libalpm/dload.c 23770 rt_sig /bin/zsh 23842 - ps opid,wchan,cmd

I get all dashes, so I must have broken something on my setup... :-( You are on 32-bit, right? Dimitris
