Subject: Zombies eat CPU?

Hi everyone,

I noticed that in FreeBSD (seen it on 3.1, 3.2, 3.3) zombies often are listed  
with high PRI (close to 100) and %CPU (often close to 10%). ps -aux tends to  
report them at the top. However top does not list them, and uptime does not  
indicate that they eat CPU time.

So is it that ps just gets invalid info due to the zombie state of the  
process, or is the 'zombie handling' CPU intensive?

Thanks

Gerd
